No. Absolutely not. We don't need something "innovative" from every system in terms of hardware. Nintendo has the Wii U and Microsoft will undoubtedly push the Kinect, so it's my fervent hope that Sony will, with the PS4, create a traditional gaming system where most of the budget is tied to the internals of the machine.
What I want more than anything is software innovation. I want more games like Journey that defy the need to slot everything into an established genre. I want hardware that's robust enough, and programmer friendly enough, that developers can do whatever wild things cross their imagination. I want games that are unique, varied, and compelling. Games are what matter the most to me.
I have nothing against motion controls or touchscreens or whatever but it's just not where my focus is directed.
