An interesting development, though I feel it's safe to say we can expect a launch of high-end GF100 based graphics cards somewhere next month Jen-Hsun Huang in his quarterly financial reports mentioned that the Fermi architecture aka GF100 aka NV60 aka G300 aka GT300 aka GeForce Series 400 will start playing a role in Q2 of this year. That means for NVIDIA that volume availability of a series of new products would be released at the end of April or early May, and not March as earlier expected.
It seems that the 40nm Fermi architecture keeps fighting NVIDIA somehow, likely due to yield related issues at the TSMC 40nm node. The good news is that Jen-Hsun Huang implies multiple product, and that covers the mid and high-end range but also professional products like Quadro and Tegra. So in the Q2 timeframe we certainly can expect a lot of new products being pushed out real fast.
