oh talking about the cores and whatnot? yeah in the rush to make launch all Xbox launch games actually only use 1 of the 3 cores. Games coming out later on in 2006 will be taking advantage of all 3 cores (as always developers just gotta learn how to do it) and they'll have more things they can do.
PS3 I guess your talking about the SPE's and all? yeah they say its harder to code for but give them about 9 months to a year after it launches and they'll have a better handle on how to take advantage of what all the cell can do
