I don't really understand why so many scoff at the idea of a "10 year plan" tbh. While even I think that 10 years might be stretching it a bit, 7 or 8 is certainly doable, you only have to look at the PS2 to prove that point. Blu-Ray might conceivably reach 100gb or more of space which offers the format a lot more leg room than what's currently offered by default in its competitors. Link
The real question is if Sony can convince developers to make exclusives for the console NOW (or even in the past 3 months). Given a few years of development time for games and the current situation of the console war how many developers are going to look at the PS3 and say "3 years from now the PS3 will have a large enough installed consumer base to warrant developing exclusives for the system."
