Sorry to spoil it for you, but research has shown, artificial intelligence does not and can not exist. All we've learned is, you actually don't need any intelligence to win a game of chess against a grandmaster. All you need to do, is to parse a suitable subtree of all moves and than evaluate the possible outcomes. Easy. Everyone could do it.
Computers execute pre-programmed calculations faster than humans can do.
But more speed only translates to higher efficiency not intelligence.
The POWER chips are up to 5GHz. Sadly you could probably still heat an igloo off of them.
We should also be seeing desktops with 4 CPU's in them not 1.
I'm sure they do, but I doubt that will be the default configuration in the new low-cost iMac.

If you push the CPU and GPU in iMacs there is a good chance you will end up killing components. Heat is a major killer of electrical components . I used to game on my 2009 iMac, as a result nearly all the components went over time, all replaced under AppleCare . Like you now I use the iMac as display for my gaming PC, if I game.
Though I have done that to MacBook Pro , just regular gaming, over time heat kills. Now days I no longer game on the macs, thier designs are awesome but due to their thinness , suffer from overheating if pushed.

After more than a year, the improvement we're looking at is a 100 MHz bump? I would prefer Apple to use "shaved off" volume on the iMac to fit in a dedicated graphic card. Why would I need a thin edge iMac but still have a big bulge at the center?

Your CPU and GPU aren't going to die from pushing it 'too hard' given that a CPU has a ceiling of 105°C and a GPU is pretty close to that - where things will start to come unstuck will be the hard disk but then again even with the best thermal protection they're still pretty heat sensitive hence in future I'm going all SSD in my next round of upgrades. Back to the CPU and GPU, if they are getting to hot the firmware will shut down the computer as to avoid damage to the hardware - if you are getting high temps then check the air circulation and the temperature of the room need to be taken into account.

Great... but what about the Mac mini?
If they update that without increasing the price, I'd buy one on release day.

I have never had a CPU or GPU die, I have had the LCD , logic board and hard drive go, all cause of the heat generated by the CPU/GPU. Look at the design, surely you realise the airflow is restricted in such a thin body. iMac are made for you average users who do not push their computers like in gaming, which is an edge case. Like I said I killed a iMac and mbp gaming, since getting a gaming PC, I have not killed my current iMac or Mac Pro. FYI the mac will not shutdown, the CPU and gpu will throttle . Only if that fails will the system shutdown .

I really hope this comes soon, and for apple to not drag its heels on an update.
Things i'd like
1- Apple to start thinking touchscreen
2- Retina Display
3- Actually allowing 21.5" users to self upgrade Memory again. (The Accounting dept is a horrible way to have the design team do things. People need to be able to upgrade Ram.
4- get rid of the glue. People don't look at desktop computers and think, "wow i really wish this was as thin as a Macbook Air" Many of us want power, and it not to be a terror to upgrade a hard drive or SSD.

My Late 2013 iMac with the 4670 and 780M run fairly cool. At idle, the 4670 likes to run around 40 C and the 780M at 38 C. When playing X-Plane, it stays around 58 C for the 4670 and 63 C for the 780M. Those are the same temps my Early 2008 17" MBP run at during simple web browsing. Nothing has died in my MBP from that heat. Not too worried about any components of my iMac dying while playing X-Plane.
Granted, I manually max out the fan at 2600 RPM when playing X-Plane instead of using Apple's overly conservative fan control.

It depends on how hard you push it. I used to play for hours with the settings as high as I could put them.
Just throwing it into google...

Great machines, but if you really push them.... they will suffer overtime due to excessive heat.

Not denying older iMacs ran hot. My parents late 2009 27" iMac runs hot.
The newer chips though run much cooler though.

Maybe the cooling got better in the new ones, cause Haswell is really bad on heat!
Sadly mine is a 2009, the same one I killed and had to get all the internals replaced.

Haswell is bad on heat if you over clock. That is where I am seeing the complaints of Haswell temperatures. Since the iMac doesn't use the K versions, shouldn't be a problem.
Like I said.... The 4670 in my iMac runs at about 58 C when playing X-Plane. That is idle temp for the C2D in my MBP. Granted the clock speed is around 3.6 Ghz according to Intel's Power widget, the CPU is only at about 30% load, and the fan is at 2600 RPM.

I am betting they redesign it to make it smaller and destroy it (i.e. make it non-upgradeable like the rest of their lineup.).

Can you link to some publications supporting this?
You'll also need to define "intelligence" to make a statement like this.

Desktop GPU's are too power hungry( aka heat) for the iMac's enclosure.

Happy to have you build one for me. Last I looked when I tried to build one it would cost me right close to the same price to more expensive. The more top end geeks that have claimed to build the closest thing to a mac pro said it cost a good deal more and was not worth the hassle.

i spent less than i would have for a similar equipped mac pro, but tailored it to me, as i need a lot of local storage , Cuda based GPUs (so SLI Nvidia) and i didn't need the ooomph of the xeons, so a lower spec i7 processor does the job,
The whole box is bigger than a new mac pro, certainly heavier, and definitely noisier , but you know what , it has two plugs, one for the PC, and one for the monitor, not a bank of plugs for all the external devices id need, i switch it off, and its powered down, all the drives are off, and the whole thing can be picked up and moved as needed without unwiring a spaghetti nest of cables.
but again, this is my use, i want a single box, with as few externals as possible, to be as fast as possible, at the task i need to do, the Mac Pro isn't that device for me, it could have been, but apple have decided i am no longer its target audience, so i had to build my own, i still have Thunderbolt 2 on board, USB 3 and a host of other nice things, sure, its not pretty, but its price/performance is what I needed it to be, had apple not gone down the Small, Sealed, and pretty trashcan route, the Mac Pro could have been the mac for all users, as it is now, its the mac for some users, or those willing to live with the hassle of "add-ons"
