Hmmm, this is hard to say. Kinect has really re-invigorated the platform I think and if (a big IF) Microsoft can deliver the software to satisfy both it's Kinect customers and Core customers then I think it will sell strong enough for the next 2 years to make a run at 100M over it's life possible.
Assumptions used while thinking about this:
- New XBOX will not be released for at least 2 years.
- Kinect stays a relevant product and increases it's own userbase.
- That Microsoft will NOT pull the 360 from shelves in it's strong territories, once the new Xbox is on the market.
