Who's ready for the Xbox 720?

So for my column this past weekend, I wrote about when we're likely to see the next Xbox (presumably dubbed the Xbox 720) hit store shelves.

My guess? Possibly at the end of 2009, but more likely 2010. Well, lo and behold, EGM reports that Microsoft is already working on a new game for the next Xbox.

The fact that Microsoft is already thinking about software makes me think that the basic hardware design of the next Xbox is already pretty well mapped out, even if I doubt any working prototypes exist yet.

Like I said, 2010 seems the most likely release date, but given the report from EGM, I'm not willing to rule out 2009, either.
