Well, then they've got 6 months (or 12 if you take into when it actually ships)
I think that we all should remember ont thing:
975 will not be an upgraded 970FX, in that sence that IBM must complete the 970FX before they can start to really producing the 975. Not like they do with the G3 series where they fist made 750, then evolved it to 750CX, then 750CXe, then 750FX, then 750GX.. each a upgraded, more refined and powerful version than its predecessor.
970 was developed from Power4, after Power4 was finished and the development of Power5 had became the number one priority for IBM.
975 is beeing developed in parallell with its heavier brother the Power5, so 975 and 970 is brothers of sorts, with parallell development too. 975 will be off to a running start, so we don't have to wait the usual one year cycle beween updates. 970 is probably somewhat of a rush job, a stop gap, an experiment.. 975 is not, so it shouldn't come as a surprise when IBM seems to be making huge strides in performance right now.
970 was developed late on 130 nm process, it was just about to be upgraded to 90 nm. That upgrade came fast, just 9 months after we first saw 970. Then comes 975 which is developed for 90 nm all along..
It was not long ago that Intel lead the MHz war by 100% or more. At the end of this year, they will probably only lead by 33% or less.
