@binary_solo: I don't think the PS base is anywhere near 60m, nor is Xbox's. They both had one very good selling point this gen: HD graphics. That and they had great 3rd party support. That's what sold the system to close to 70m gamers. If Nintendo only has a 20m base, do you really think PS360 has 60m each? No. =)
OP: I agree that if Nintendo plays this gen right, and the other two mess up Nintendo will win. If all consoles will have the same 3rd party support (which I think they'll have - see my sig for further info) I think there's a big chance of WiiU winning this gen.

Furthermore, I think VGChartz should add a "Like"-button.
