Q: Is Revolution "two-to-three times more powerful than GameCube?
A: USA Today reported this news based on a comment from Nintendo of America's vice president of corporate affairs, Perrin Kaplan. The information was later determined to be false. We do not yet know how much more power Revolution wields over its predecessor.
