The regular 780m is a vast improvement from the 680m in terms of performance, it performs close to the Titan in 1080p Applications. Whether the downsized version for the iMac (MX) will see such a boost is what is speculative.

That is just crazy talk, the GTX 780M performs nowhere near the Titan (I'd expect 60 % or less of Titan's performance from preliminary benches*). You must be confusing it with the desktop GTX 780 (which indeed is a decent step up from the desktop GTX 680).
*According to AnandTech, the GTX 780M hits 41.5 fps in Bioshock Infinite at max settings at 1080p. The GTX 780 hits 95 fps and the Titan 104 fps.

What are you talking about?
First off; What Zandros said.
Secondly; the 680MX is not a downsized version of 680M, it's in fact the opposite, it's a beefed up 680M. If 780MX is released, it will most likely follow the same pattern and be a beefed up 780M.
Can someone who owns one comment on the screen's anti-glare? How does it compare to the mirror iMacs and the old school matte screen iMacs?
I've got my fingers and toes crossed for a model above the 780M for use specifically in all-in-one PCs (780MX? 790M?) that's a Titan with lowered clocks to meet the iMac TDP requirements, just like what they did with the 680MX (identical to the desktop 680 but with reduced clocks).

The problem here is that the 700-series is based on the same Kepler architecture and lithography as the 600-series, so all the extra performance comes with a corresponding TDP increase.
The GTX 770 is based on the GK104 chip, same as the GTX 680, and has slightly better performance. However, the TDP for the 770 is 230 W compared to 195 W for the 680.
I imagine the TDP for the 780M is about the same or slightly higher than the 680MX's TDP. Obviously the process is more mature, but on the other hand clocks are slightly higher.
So, to get a hypothetical 780MX in there, Apple has to feel that the iMac enclosure/PSU is capable of handling more heat/power draw than the 2012 models already do. Perhaps it does, I certainly hope so.
You know what puts me off getting an iMac?
No easily upgradable SSD.
I can live with everything else being sealed. The upgradable RAM on the 27" is nice, but frankly RAM usage isn't mushrooming like it used to, 16GB doesn't cost to much and is likely to do me for a few years...
However, ~1TB SSD drives are just starting to show up (only 2.5" so far, no mSCSI or similar boards - but they will surely follow). I don't want to blow a couple of grand on a computer with a measly 256GB SSD or a stop-gap fusion option that I can't easily replace with a terabyte-class SSD in a year or so's time when the price drops.
That and the fact that the jury is out on how long a SSD will last. Hopefully, in practice, it will last for years and fail 'gracefully' as blocks start to wear out, so I'd like the option of easy replacement.
Stick a hatch in the back for something like a mSCSI card (or, better still, expose the HD bay) or no sale.

Yeah I see what you mean. I also just noticed the TDP for the desktop 680 sits at 195W vs the 780 at 250W. Given that the 680MX in the iMac draws about 122W, you could extrapolate that this theoretical 780MX could draw in the neighborhood of 155W.
What I would really like is a mac "semi-pro" or a boosted mac mini. One with one or two x16 pcie slots, two HDD/SSD brackets and four ram slots. They could sell it as a bundle with one or two 27" TB display only if they want to restrict it to a certain "wealthy" market..
The real "pro" would still be available with xeon E* cpu and ECC for the real heavy workload, but we wouldn't have to compromise on performance when opting out of the mac pro option.
Presently I'm stuck on a PC due to 3D rendering and video transcoding. I would love to trade my 2010 iMac for a new 27" but I would do it at a drop in my productivity.

Why does everyone keep thinking that?
If i know Apple whenever they push back a refresh they are likely to keep it there. Like the iPhone 4S fall release. So i say Nov, Dec Q4 if nothing happens around WWDC.
yeah i meant 780, not 780m. Stupid Nvidia and their letter classifications that are too similar for me to remember
----------
What i meant to speculate was how much better the 780MX will be over the 680MX. Speculating that it will not be the kind of improvement that was seen from the regular 680 to the new 780
It's not amazing, but it's a definite and visible improvement over the previous glossy displays. Nothing at all like a matte display. I switched from dual 30" matte ACDs to dual 27" (iMac and Thunderbolt) glossy at work. That was a huge change and I miss the matte (bad glare from the windows in my office). We've since bought a few of the new anti-glare iMacs and the difference is worth upgrading. I'm just holding out until the next refresh before I replace mine.
People are expecting a spec bump (Haswell, Gigabit Wifi, etc...). Not a completely new redesign.
Totally agree and there will be a update later this year. Those that are denying it are just blinded by next years bigger updates.
Here is what i think the 2013 will have:
Given:
Haswell CPU
780M/MX NVIDIA GPU/AMD 8970M
IEEE 802.11ac
Likely:
960SSD BTO Crucial
1080P FaceTime Camera
Unlikely:
6 core beast.
Retina.
16 RAM standard
Arrival:
Either WWDC (kinda unlikely) or Nov-Dec.

I seriously hope the new imac does not come out with touch screen.....I mean I struggle to keep the finger prints off the one I have
Gestured or Siri controlled is the next step I reckon.

Anti-Glare Screen ?
Hey Nugget -
Approx what's the upgrade cost on anti-glare? I don't see that on the website. Would you need to call or visit a store to do that?

Oh, I don't think there's an upgrade path or anything. I meant I'll buy a new iMac with the anti-glare screen for me and then someone else in the company will get my hand-me-down mid-2011 iMac.
Considering the iMac has always been based around the screen it's it's much Apple could do to the design and still make it look like an iMac.
About the only thing left to do is reduce the 'chin' but really where would they put the Apple logo if it was removed?

An illuminated Apple logo at the back of machine would answer you question much like that of the macbook.
But not being a laptop Apple would want the logo on the front considering a large number will likely be against a wall and no one will see the back.
