On his last week's Q3 conference call, Jensen said that their next generation chip that comes after 55nm is going to be a new architecture.

He didn’t really say how new and how revolutionary the new architecture will be, but we can hope that it will get Nvidia back in the game. It was rather interesting to see that Jensen didn’t want to comment if that chip will be 40 nm-based, as they tend not to comment about non-announced products.

This is probably going to be the most important transition for Nvidia in its recent history, as if they win the performance crown back, they will be fine; but if they fail, ATI will grow to the next level.

The new chip comes in 2009, which is as much as we could get from Nvidia’s blurry statements.
