Is Nintendo always going to be behind Microsoft and Sony in graphics?

[ph4nt]

All rumors are pointing to Power 7 and R700 GPU. This would put it roughly 5-6 times the raw computing power of xbox 360/PS3.

MS and Sony are going to have to throw a lot of money to get a system that makes the Wii U look obsolete like 360/PS3 vs WIi. The most I see them doing is releasing a system with a 6900 equivalent, and even then the actual difference in graphics quality would not be too noticeable since we are reaching the point of diminishing returns.
