Really, becasue it's the most established of the next-gen consoles. Devs have worked out how the console works, given they've had a couple of years and at least a couple of titles under their belt, so I figured this would be the best time to get one. They know how to make software for it already, so from now on I guess they'd be pushing the envelope, getting more and more out of the machine.

This is the x360's golden age. That's why.
