Não faço a mínima ideia da fiabilidade deste site mas...parece que se for verdade as coisas não estarão muito boas para o lado da nvidia.

Now it is time to peer into the giant crystal ball of semiconductor scheduling. Lets assume that the chip taped out on work week 28, more or less July 15. TSMC runs 6-8 weeks for a 'hot lot', but our moles say currently it is much closer to 8 than 6. Add in just over 2 weeks for initial card build, bring-up, testing, debug, and making any fixes. Lets just call it 10 weeks, October 1 or so.
If everything goes perfectly, and the GT300 is literally bug free, or possibly having only minor bugs that Nvidia is totally confident can be fixed without causing any more problems, then they can start running production silicon.
From there, TSMC takes 10-12 weeks to run 40nm wafers, there is a lot to do on those parts. If we are optimistic and say 10 weeks, and add another two for the initial board manufacture and shipment, we will be at a total of 22 weeks out. This means if everything goes perfectly, not so much as a hiccup, we are looking at mid-December for the first syphilitic trickle of parts.
The chances of this happening are somewhere around zero though. Nvidia can't make GT215s in volume, and that chip is about 1/4 the size of GT300. Toss in that this is going to be their first GDDR5 part, their first DX11 part, and their first part on a new and untested architecture, and you are likely to have at least two spins.
Each spin is the same 8 weeks as the last hot lot. Adding one puts production silicon out of the door, with the previously alluded to trickle, in late February. A second spin puts it into Q2. If there is anything more, well mid-year is very likely. Smart money is on at least two spins.

Mas não deixa de ser boa para comentar. Até era bom a nvidia poder lançar a GT300 ao mesmo tempo que a ATi lança a RV870, pena é o tamanho do GPU ser similar à GT200.
] e caso a relação preço/perfomance fosse semelhante, visto que assim ia ter acesso a drivers de qualidade [pelo que se diz, comparando com os da ATI] e CUDA...
