If Sony doesn't use an upgraded version of the cell, they might as well leave the console business because no one will want to make games for them. They already pissed off a lot of third parties because the cell was difficult to program for and Sony didn't have very many tools to lend out to ease the process and what they had was expensive. By then the nVidia 280 will probably be dirt cheap and they will use that or something more powerful. Ram is already cheap so they could go 4gb or higher if they wanted. Also, as fast as hard drives are dropping in price they could have 2 tb of hard drive space in there.
edit- forgot blu ray, how dumb of me. I don't think it will be 200gb like I think someone said. But it should be 100gb (4 layers) and easily twice the speed, but should be three times the speed.
