Ade Hawkins: Much has been made regarding the rumoured power - or lack thereof - of the Wii U. The truth is, Nintendo can make those chips sing. It isn't about how many teraflops of data you chuck around, it's what you do with them. The Vita is supposedly far more powerful than the 3DS, but it's soulless (with tiddly analogue sticks). So don't worry about whether Wii U has an outdated GPU or 1GB RAM. Worry about how amazing Super Mario Galaxy 3 will look in HD, and the added dimension that controller will provide.
