Next generation there won't be many AAA exclusives*

I agree. I think all games will be able to support a wide range of battery types.

Anyway, since the Wii 2 will likely be slightly more powerful than the PS360, and the PS4720 will also be slightly more powerful than the PS360, you're increasing your selling base by 50%. The push for graphics probably won't go much further, and dev costs for the same level of graphics will fall. So not many games will have big budgets, that's true, but you won't be able to tell the difference - a medium budget game next gen will be equivalent to a high-budget game this gen.
