Following up with my earlier comment, why are people so sure that more processing power will help the XBox 720 and PS4?
The DS was almost "a generation behind" the PSP, The 3DS is almost "a generation behind" the PS-Vita, and the Wii was almost "a generation behind" the HD consoles. The outcome of these "console wars" was determined more by which system launched first, was able to attract better third party support, and/or was a more affordable system with lower priced games.
Releasing a system 12 months (or more) after the Wii U, at a higher price, with games that take longer and cost more to develop does not seem like a good strategy for success given recent trends in gaming.
