Can we get speculation about what the next Imac will bring? I may be waiting on the next one before I go Mac. I'd like to go ahead and start dreaming on what it will be like. :)

That would be nice.

What about target display mode? Think it will make a comeback?
If it has been requested enough and Apple adapts TB3/dp1.3 then yes I think it will probably support target display mode, the main reason now not to is that it would require MST connections and I don't think Apple wants that as it is messy.

I would be surprised if Apple offered a UHS-2 compatible SD-slot as well, but would be thrilled if they did (300MB/s speeds)

AMD Polaris for the 27 inch and the 21 inch will maybe get sky lake if Intel produce desktop chips with a good iGPU. Other than that you'll get USB-C/TB3 ports and that's about it. Canonlake won't be with us this year so there is very little in the way of better tech available.

Kaby lake though should be available, so why settle for skylake for the 21.5"?

Kabylake is just rebranded skylake practically no difference and not anything I consider an "upgrade" slightly better 3D graphics and 4K video playback will mean nothing on the high end chips Apple uses (if they even do Kabylake versions of them it might not be worth intels effort for the higher end stuff) and built in USB 3.1 support doen't mean a lot.....

Not much to speculate. Skylake on both the 4K and 5K with TB 3 and USB 3.1 support. Bump in CPU and likely a 10% bump in graphics. That's what's likely

Possible is a redesign -- especially if the entire Macbook line gets a design refresh and possibly a 'tock' back to Nvidia with a much greater jump in graphics power on the dGPU models. About a 10% chance of either happening.

Kaby Lake will be built on a smaller process so it will run cooler and possibly clock higher.

As to "slightly" better GPU - intel has been making huge strides in integrated GPU as of late, so i would say that 30-50% improvement would not be out of the question. That's not "slight"...

Unfortunately you are misinformed the smaller process won't happen until canon lake (10nm) Kabylake (14nm the same as skylake indeed the same architecture on CPU) will stay the same as skylake with very small changes to graphics architecture that promise very small improvements.

Basically they are having trouble with canon lake and have departed from their tick tock release schedule to provide something new this year no matter how pointless. Canon lake won't be out until late 2017.

All this info is freely available on Wikipedia you should do your research before making assumptions.

I find the current design strange. How they just took the last design and made it skinnier. Realizing Apple's focus is off the mac I really wonder if it will get a redesign.

An Edge to Edge just a screen computer is probably possible now

Hopefully we will see the return of adequate ventilation so your machine doesn't fry itself after running for an extended period of time under sustained load. This would also cut down drastically on fan noise since they would not have to run at maximum RPM to keep the CPU/GPU from hitting 100 C.

And presumably Hank is talking 100C ( 212 F ) not Fahrenheit. Apple's adoption of thinner iMacs ( compared to say the 2011 version which was thin enough IMO ) results in higher operating temperatures which, no matter how it's construed, isn't good for electronics. My 2011 27" iMac runs under load at 118F ( 47.8C ) and only 91F at idle or minimal usage without blaring cooling fans. I'm guessing ( but seems reasonabe ) current iMacs would run cooler in a form factor like the 2011 iMac. Tells me a lot about what Apple thinks is important.

I swear that if I ever bought an iMac I would drill a series of ventilation holes in the back to keep the interior from frying itself. I don't see the point in sacrificing functionality and reliability for good looks. That's counter productive and indicative of a bad or failed design.

My 2015 iMac runs at the 34c range, and pushing with some work raises the temps by 10c. I'm sure playing a game or something really intensive will cause the CPU to get a bit hotter, but this iMac has been the coolest computer I've had in a very long time.

Reviews have also backed up my experiences as well, noting that the fan ramps up less, and does not throttle like the older models had too.

The latest 5k iMac runs cooler than the previous model, mainly due to Skylake and adjusted fan speeds. It no longer throttles, but still runs uncomfortable hot.

Try running Premiere, Resolve or any other package that heavily utilizes the CPU / GPU and you will get very different readings. Running components at high operating temperatures for prolonged periods of time will cut down on their life expectancy and reliability. The simple fact is that Apple removed most of the ventilation for aesthetic reason. In recent years they have developed an unhealthy obsession with thin devices that is coming at the expense of functionality and reliability.

Thanks for sharing those temperatures; very helpful.

It's clearly an improvement...

That's what it looks like to me but I'd really like to hear the Apple engineers weigh in with their technical reasons ( other than Marketing forced us to do it ) for adopting a thinner form factor.

Jony Ive gets what Jony Ive wants.

It's really that simple.

Probably because it won't have a fast iGPU for the 21" iMac, which is why they're currently Broadwell.
Seen any roadmap which says Kaby Lake won't get Iris Pro 580? Then again, Skylake gets it soon, so Kaby Lake will probably get it a few months after release as well, pretty much too late to show up in any late 2016.

i suppose this is why macs (according to consumer reports) are 1/3 less likely to fail in their first year and over three years are half as likely to fail as their windows counterpart? so they get hot under a heavy load. the fans ramp up and they cool down. the current imac is fantastic and there is no windows machine that comes close imho. there is no evidence that these have design flaws that will shorten their life. not to say apple doesn't make mistakes, they've made plenty. but this, so far, knock wood, doesn't seem to be one of them.
