It's clear you have no idea of whats avaialble on consoles currenty. If anything PC games need to catch up with consoles in terms of innovation.
If by "innovative" you mean the endless deluge of music and fighting games, then yeah, I guess PCs are lagging. Outside of that, I challenge you to find ONE console game whose concept wasn't done first - and better - on the PC. And beyond that, the PC still has a lot of innovation to offer - I highly doubt you will see original efforts like Mount and Blade or Operation Flashpoint on consoles. Everything on a console has to be easy to pick up and understand, and as a result every console game is lacking depth. And I say this as an owner of a PS2, Xbox, and Dreamcast (which, coincidentally, had some of the most innovative titles for a console in a long time).
