Original plan has always been "March" (end of Q1 2010) for high end and mainstream soon after... since goodness knows when...
IF they can get the GF100 onto a successful sub 40nm process it would massively open up the possibilities.
NO, it hasn't and to constantly so something so ridiculously untrue that NO ONE at NVIDIA backs up your story is an entire joke.
THe article is saying MAINSTREAM FERMI is not delayed, not the high end part, GF100/Fermi the release in March is not the Mainstream Fermi, they mean a half sized 5770-type part. They are saying that's on time, largely because Nvidia don't release their mainstream/midrange part within a month or two of high end, they are always 6 months later with it, right now its on time because they aren't late, when they miss its release, it will be late. Midrange parts that have no profit will be pointless, yields won't match the 5770 while being circa 50% bigger.
Considering Nvidia, the CEO, and everyone there made a huge big launch saying there would be volume availability on a specific date in November, for one lone Nvidia guy on a forum to say, its not late, is ridiculous. Nvidia themselves today don't say "we aren't late, we always planned on a March release" because its untrue. They also admitted delays and lateness in their recent "architecture" release. The fact that the industry didn't expect it till March and hasn't for a long time, doesn't mean its not late, they just expected Nvidia to screw up again and again. Nvidia hoped to release at A1 silicon, than prayed for a A2 release, and then prayed on a A3 release, which they might get.
Nvidia and AMD are both working on anything up to 3 generations ahead ALWAYS, so working on their next generation is no surprise and never will be.
Anyway, TSMC won't have a decent 28nm yield by the end of the year, if they can make anything launchable this year I'd be shocked, they've switched from gate first and a far better quality process to a gate last version, which introduces a bunch of problems but is cheaper and easier to get going, but much worse. Half of the issues with their 40nm process are being carried over to the 28nm process. IF thats late, Nvidia are late even if their chip is completely ready, when TSMC are finally ready, we've got to pray to the process gods that Nvidia don't need 3 spins to get it right, if they do it will be VERY late again.
