How likely is it that this lands before The Witcher 3?
I think its very likely. Witcher 3 is feb 24th after all.

I don't think GM200 can have as big a leap over GM204 as GK110 over GK104 because there isn't enough die space left moving up from 398mm^2 to accommodate all the compute-specific transistors on top of more memory controllers, ROP's, and SMM's. GK110 had 87.5% more cores than GK104 and a 250mm^2 larger die size. In my mind (before this thread was started), I was thinking GM200 could maybe squeeze out 50% more cores than GM204, adding up to 24 SMM's and 3072 cores. I still think that is a possible outcome. 22 SMM's make no sense because nothing adequately divides into 22 for balance purposes, and since 20 is a rather small (25%) increase over GM204's 16, 24 makes the most sense to me.
But 50% more cores, ROP's, and bandwidth != 50% more performance. I think 35%, maybe 40% max more performance than GM204 with a real-world power usage slightly lower than GK110 is both feasible and reasonable for a fully functional GM204 chip. On top of that, I think GM200 is going to come before GCN 2.0, so I think Nvidia will slow roll GM200 just like they did with GM204. If it is to have 24 total SMM's, I think Nvidia would release a gtx 980 TI with 20 SMM's active and DP castrated. Titan II would have 24 SMM's and full functional DP operation. Then later on Nvidia will release a full functional, DP castrated GTX 985 (or whatever) to combat a new high end AMD chip, or if no chip exists, just to get more sales at a higher margin than 980 TI.
TL;DR I think GM204 on 20nm will have a slightly lower TDP than GK110, but will not be quite as much a jump over GM204 as GK110 is over GK104. I also think GM200 will have some serious OC headroom just like GM204 has, and I think Nvidia will slow roll GM200 (introducing harvested dies first) like they did with GK110.

I highly doubt that we are going to get a 20nm chip though - TSMC is only offering 1 process for 20nm. Reportedly the 20nm process was only 10% faster at high power for a given level of power consumption than 28nm. So I expect high power to jump straight to 16nm FinFET, unless they change their plans.
I can wait then. Seems like this is the card to get and considering SLI has been worthless for me I'll just grab a 980 Ti.
Tech wise if they do release a Titan II, how much video ram could they realistically put on it? The Titan I had 6gb, do you think they might up it to 8gb or even 10gb?
Everybody wins... except people who buy the 980 now.
We'll see if the GM200 is priced like Titan or like the 780 Ti. If it's another Titan, who cares? But if it will be priced like a 780 Ti, then the ones who bought a 980.. well, feel sorry for you.
I'm guessing the pricing will depend on AMD. I was surprised not to see anything of consequence from them, after their "watch this space on 25th sept" tweet.
They already won by buying now.
Else you can postpone upgrades forever because something new is always coming in the future.
970 = incredible perf/w/price
980 = incredible perf/w but is $100 too expensive
With OC, you can get the 970 up to stock 980 performance for $220 less... almost enough to buy a second 970 for SLI (if you like that sort of thing). The 980 is being marketed as a flagship card even though we all know that the real Maxwell flagship will be here in a couple months. Seems like if you're really anxious to upgrade, get the 970 now, because when you go to sell it in three months for the 980Ti, it won't lose as much value compared to the 980.
There's always newer and better around the corner. It's just how much better, for how much money. Am I going to get my money's worth out of it, for the 2 years I intend to keep it?
I just meant that as a way to make a judgment call.It was 2½ years since I got my GTX680 that the GTX980 replaced. So its certainly possible.
