To be fair, both the 360 and the PS3 have 21 buttons plus two analog sticks, and that's not counting things like pressure-levels on the triggers on the 360 and and on the triggers and the four face buttons on the PS3, or the Sixaxis functionality on the PS3 which is also analog (more or less infinite input possibilities on each analog item, like a mouse).

And that's not accounting for functionality when using two or more of those buttons at the same time.

I'm just sayin'. ;)
