you got very interesting points devguy...
first of all..mircrosoft needs to have the 512 ddr stick of ram...to be on the safe side.....i don't think having 3 cpu's on the xbox2 will be true at all...not unless they are willing to sell it around 600.00 to 900.00 bucks and they would still be losing money.
also...not having backwards compatability is a big no no...mircrosoft is going to shoot its ass if they don't have it....
about the hardrive...it would be very convinient for the xbox2 to have a built in harddrive...that's what make it different from ps2...that flashmemory thing would just suck and cost a lot....
i just hope they make the right decisions...else we are going to still see ps2 be in 1st place like usual........ :P :)
