FUD Zilla claims we may already expect the first 40nm GPUs from NVIDIA in March 2009, but the site doesn't know whether it's a low-end, mainstream or high-end part.
Of course, this is the best-case scenario and if something goes wrong, the schedule will have to be pushed back, but let’s be optimistic for a moment and hope for Nvidia’s sake that everything will go smooth this time.
Nvidia has hoped to have its 40nm chips earlier but due to some delays caused by TSMC this will have to wait at least until March. After Q2 2009 there should be even more chips from Nvidia and ATI in 40nm as they both plan to make this transition roughly at the same time.
Nvidia is likely to get to 40nm first, as ATI might wait to see what Nvidia has up its sleeve as it currently has the dominance with its 55nm but it should follow shortly after Nvidia, or roughly at the same time.
