Why would you need 512 MB video cards? I can think of a few good reasons why not to release 512 MB cards.
1. No body buys $500 256 MB video cards. Therefore nobody is going to buy $600 or $700 512 MB video cards.
2. Most games don't even really need 256 MB. You would need FarCry set to 1600X1200 with max AA and Ansi to even see the benefit of a 256 MB card. Which is why a Radeon 9600 Xt with 256 MBs is a joke.
3. Only reason people got worried about 512 MB cards is because of Doom3 ultra quality setting. Which uses almost no texture compression. With ATI's 3Dc and DXTC I don't see much of a reason to use uncompressed textures. If we're not using texture compression we're moving backwards not forward.
If you're one of those people who own a 256 MB Radeon 9600 or Geforce FX 5600/5700 I'd be more careful where you spend your money. Unless you plan to run games at 1600X1200 with all the goodies turned on the extra memory isn't going to be helpful. Not just any games but FarCry and Doom3 are the only games I've seen that really need 256 MB. Doom3 doesn't need 256 MB if you compress the normal maps.
on the other hand if you are like some people (including me), "the money is not an issue" type of guy then it certainly won't hurt to have 512 MB
I was hoping for a 512 MB board this winter
a new patch for Doom 3 and a 512 MB gfx and I'm ready to play it through once more at 1600x1200 4xAA716xAF ultra quality
about the reasons for not releasing the board I think you can see that logic simply doesn't apply to this
there's 256 MB FX 5200 non-Ultras out there with 64 bit memory buses basically they can't even run shit with AA/AF disabled, much less with it enabled in high res in the latest games (which as you pointed out is the only situation where its really needed)
yet they exist and nvidia and ati sells loads of them
I work for a reseller and I see this every day, people look at our selection of videocards and when they get to choose between a 5600 non ultra 256 MB and a 5700 Ultra they go for the 5600 since it has more memory
just like a lot people go into the store and rather buy a 2.4 GHz Celeron than a 2.0 GHz Pentium 4 even though the P4 kicks its arse
as for nobody buys high end videocard, lots of people do depending on where you live
in europe the high end market is a larger chunk of the market than it is in the states or asia
the nordics for an example, we have loads and loads of high end boards going out through the "home PC program" (buy a PC through work and you get it tax free)
also you might be thinking about the low percentage of high end boards nvidia are used to talk about, fact is that percentage is much higher when we're talking ATi
of course most of this is OEM sales, not retail
and last but not least, when the 512 MB boards are released there will be a price cut on the 256 MB boards, it goes without saying
it's always been like that: the refresh pushes down its predecessors price point
basically it just "takes over" the price point of the current 256 MB X800 and 6800 boards, pushing them down a notch
