I'm interested. Microsoft are the last of the 'big three' to reveal their plans, and with PS4 being essentially a more developer-friendly gaming platform to make games for, hopefully Microsoft have something up their sleeves that's as fresh a change as the Wii U GamePad is. Maybe Kinect will actually fulfill its promise this time? Who knows.
But with Microsoft's focus on the next Xbox being a "do everything" box, I'll be watching closely as to what they've come up with.
And I'm hoping they've paid off a few Japanese publishers to make games for it (i.e. they haven't given up on Japan), but we probably won't see any third party games until E3. The new Xbox event appearing on Japanese Xbox dashboards does at least provide some relief as to whether Microsoft still cares about Japan...
