If this info is true, then we should not see hyperthreaded G5, but dual core G5.
This dual core G5 will be huge chip,even, bigger than the power4 (even if there is no L3 cache manager, there is two altivec unit : one for each core).
I day it's not impossible to see such a chip, but I am surprised that they do not create an hyperthreaded G5 who recquieres much less transistors (but who will be less performant either).
This G5 MP, will produce lot of heat. It may be possible to see one in a desktop with the 90 nm process, but we will never see them in an I mac or a powerbook, unless they will be fabbed on 65 nm process.
