Oh, and I do see MS dropping support for the 360 shortly after the NeXbox is released. And not because the 360 is losing them money like the original Xbox, which it no longer is, but because of a lack of 1st party studios. That's not to say they are going to stop selling them, but they are definitely going to drop personal releases on the system to a bare minimum. In fact, I think we have already started to see the beginning of this. This year, the only notable games MS released was/is going to be GeOW3 and Halo Anniversary. Next year, it seems they will only be releasing Halo 4 and Alan Wake 2 (the later not being a huge game, but still a recognizable exclusive). They have probably already started developing games for the NeXbox, while a sparse few are focusing on the 360. Next year will probably be a pretty good year for the 360, but MS are probably going to be relying on Halo 4 (not developed by Bungie, so have to see how that turns out) and a cut for the 250GB model to $249 or $199.
Sony, on the other hand, have always supported their previous consoles, and next year is showing the same thing. Some studios have no doubt started developing games for the PS4, but next year the PS3 will have Starhawk, Sly Cooper 4, Twisted Metal, The Last Guardian, a new GOW game(?), new Quantic Dream game(?), and Sorcery(?). The last 3 have ?'s because they are not 100% confirmed, but are extremely likely. I'm also pretty confident that Sony may cut the price of the PS3 by $25-$50 late in the year to help combat the newly released Wii U. And while none of that has anything directly to do with the PS2 sales, it is going to tempt a lot of gamers to jump over to the PS3.
