Well everyone thought it would be available by Win 7, but Ati were saying it would be sooner than you think so wouldn't be surprised to see them before then at all.
It looks like Nvidia's dx11 parts are a good 6 months away if not 8-9 months. THe laughable excuse of a dx10.1 card from Nvidia coming with 40nm in maybe August or later, are going to be, wait for it, 24 stream, and 48 stream parts.......... meaning 2 in sli will give you half the juice of the original 260gtx, ok at least Nvidia finally have some low end up to date cards to compete with. No idea why they've so completely ignored the segment for 2 years.
Just a kick in the teeth that a LOT of whats going to be great about dx11, should have been in dx10 in the first place thanks to Nvidia
I don't like Nvidia, their practice, their paying off game dev's, but I'll still buy one if its majorly faster. Finding it hard to imagine them competing when bringing out a card thats going to be sooo damn late. The more we shift into programable shading styles, the easier and easier it will become to leverage the full juice out of the "units" of shaders that ATi has and the less of an advantage that single shader units have, so Nvidia's huge expensive cores really isn't the way to be going right now.
I honestly hope Nvidia have had a large redesign and have gone more ATi like with a small efficient die, otherwise they'll be overly expensive again and while AMD/ATi have done the right thing and priced very competitively rather than undercut Nvidia by a bit and make more money, how long they can continue to do so I don't know.
