Probably.
Both points have been in this thread, while weak cores, it will force devs to think in more threads, yes the old consoles supported 3+ cores/threads(ps3 "threads" is in limbo in this comparison, spes <> cores) but they wasnt x86, and yes a weak quad could rival the upcoming 8 core consoles.. but the architecture and code designs/patterns that is going to emerge from the new consoles should be easily transferable to our desktops.. On *this* side of things, i predict good times ahead, and I hope it will push/set a standard for future code parallelism.
