RUMOR: The Nintendo Wii's successor is going to be two times more powerful than the Xbox 360.
FACTS: "The Wii2 will probably have an ATI R700 series GPU," Geekti.Me reported. "The R700 series GPU has a clock speed of 900MHz. PS3’s RSX clocks at 700MHz, and the 360’s sports 500Mhz. This puts the Wii 2’s graphics at, tentatively, 30% more powerful than the PS3 and 80% greater than the 360."
This rumor has been around for ages... but it looks as if it's going to become a fact! But keep in mind that even if those specs are true, it doesn't take into account the amount of memory the motion controls will eat up. So in theory the Wii's successor may only be 50% more powerful than the Xbox 360.
