I normally hate speculation about future computers just after a new one has been released but can't help thinking that if only the new MBPs had USB3 and could take more then 8Gig of memory I would be comfortable buying one and thinking it will last me 4 years or so. At the moment, without USB3 (even with Tbolt) I can't bring myself to buy one. Just spoke to an Apple sales guy and he said he didn't think Apple would ever use USB3. I can't believe this is true but scary if it is. Am I correct in thinking that the next set of support chips from Intel will be 'native USB3' (what ever that means) and in which case it will be hard for Apple to have USB 2 only? I personally really want USB3 on my next MBP even if Tbolt is fantastic as I have a funny feeling USB will still be very handy for a long time! Regarding memory, does anyone know the limiting factors regarding memory in the MBPs - is it simply physically how much memory they can put on the chips or an addressing thing or something else. More specifically, do you think the next generation of MBP (Iverybridge I think) will take more than 8Gig of memory?
