So the Kayla board announced today has a GPU, which, according to AnandTech, is a 1 SMX Kepler chip. Does the GK208 have anything to do with that chip?
Highly probable Kayla has a GK208 GPU:

SM35 is a full GK110 feature set?

It can keep the "GTX Titan" name while Geforce 700 series get launched as "lesser" products.
A Titan with one more SMX disabled and 320bit might end up with a 7xx name such as GTX 775 w/ 2.5GB, maybe.

It might be partial, such as dynamic parallelism and no HyperQ.
But here we have a table that says which GPU support which "Compute capability", GK107 is 3.0 and GK110 is 3.5, surely SM35 means the same as compute 3.5

If there will be 7xx-series from Kepler-based products, they'll be rebrands or possible clock-tweaks, new chips? Not going to happen (besides the GK208 which could be the Kayla-chip)

AnandTech posted a correction the Kayla board has 2 SMX 384 CUDA Cores.

As Kaotik said they can do new brandings and not do any new chip.
Though, a new branding and clock is sometimes decent (9800GT or 9800GTX to GTS 250) or entirely pointless (8800GT to 9800GT).
The high end would look weak I think, with GK104. A GK104 GTX 780 looks pointless, or doesn't have very good value : they should do a GK204, which I speculate to have 10 SMX and a 384bit bus, and no ECC in the caches (etc.)
Geforce GTX 700 series would thus use GK208 (and possibly GK107), GK106, GK104 (even if some "ti" model), GK204.
I have of course no grounds to base this on. Rationale for not doing a GK204 is AMD keeps its Tahiti at high end, and nvidia thinks a very small clock boost on GK104 is enough.

While I think it would be a great chip if it were to happen, I just don't see Nvidia using their engineers to create a new Kepler high end gaming chip. There is another GK110 Geforce card coming this summer: http://translate.google.com/transla...nedbantat-geforce-gtx-titan-med-gk110&act=url.
A 10 SMX 384-bit chip would probably exceed this card's performance because of better bandwidth and higher core clocks / ROP throughput and also encroach on Titan territory to the point of making Titan look absolutely worthless (instead of just way overpriced). Nvidia has 4 Kepler chips, I don't see them creating a fifth one just to sell to gamers. I think the cutdown GK110 in the link I provided will be the gtx700 series flaghship (gtx780 or gtx785). GK114 / GK204 (whatever Nvidia calls GK104's refresh) will probably just be transistor optimization tweaks, nothing extraordinary. I expect about 5-7% faster than gtx680 with a slightly lower or same TDP with the gtx770 label.

But at what price point ? Untill they decide to decrese the price of Titan, + the second slimmed GK110, this will put a GTX770 at 550+ $..
nobody will buy a GTX770 with 5-7% more performance of a 680 ( so in the overclocked retail 680 territory) for 550$.
GTX770 = 550$, GTX 780/GK110 = 700$ and Titan 900$ ? Because i dont see them release a cut down version of Titan GTX780 @ 550-600$ for get their 770 at 450$ with the full titan still hovering at 900$ .
I mostly think they will release the slimmed version outside GTX 700 series.. for offer a lower priced Titan, but still keep the card at something around 750 $ .

There probably won't be GK114 or GK204, but just Maxwell in 2014, just like AMD isn't making new "refresh line".
OEM rebrands might happen.

So, Geforce 7xx could be a "lost generation", like Geforce 3xx, and then Maxwell could be the Geforce 800 series.

I'd say that's certainly a possibility, especially if Maxwell initially launches on 28 nm early in 2014 (there seems to be little point for a "GK204" in late 2013 if "GM104" shows in Q1/Q2 2014). If GK208 comes to the desktop/notebook space, then GK208 could be like the GT21x series—just low end chip(s).
I'm in the camp that doesn't think there will be a GKxxx chip between the 104 and the 110, and I'm not convinced that a GK114/204 (if it exists) will have a different core count and memory bus width than the GK104. If GK104/114/204 doesn't increase memory speed past 6 Gbps, then I bet that it'll have little or no core clock increases and a fair TDP reduction instead. They'll probably keep one or more Titans for the high end, at least until Maxwell.

Even if so, could it migrate to the desktop/notebook space later?
Sure, why not, if it can fill a gap from nV's lineup
Well a 320-bit 13 SMX GK110 at slightly lower clocks than Titan will have a significant decrease in performance over Titan. The bandwidth cut + less ROP's + lower clock speed will put a significant dent in performance. I'm also guessing the DP performance will be castrated like on every single previous high-end Geforce card before Titan. I think $599 is a likely price point, with GK114/204 coming in at $449, creating the same $150 price point difference like with gtx580 and 570, and gtx480 and 470.

I'm a bit surprised the TDP is the same as that of the 660. I thought it would be at least a bit lower.
