AMD is being awfully secretive with their release date of Bulldozer chips. I think this piece of info you linked absic has been out there for a while. The problem is, as you've mentioned - what the heck's going on with the desktop version which, so far, is supposed to be released in Q1
.
On the other hand, I wonder how Intel and AMD will fare in a few years if the current trend continues. I mean, there's
nothing out there that requires more than what medium-level quads from the Core 2 Quad and Phenom II x4 lines can offer. At least for about 90% of users out there. Better yet, most people would be perfectly satisfied with reasonably clocked dual cores.
Basically, hardware is progressing substantially faster than software at the moment. As it is, Thubans and i5s, i7s are already an overkill and should cover everything for the next 2-3 years without problems.
Myself, I'll likely skip Bulldozer/Sandy Bridge generation altogether. As I doubt I'll have any use for that much processing power.
