Which of the Big Three (Nintendo, Sony, and Microsoft) is True King of Exclusives?

[Reasonable]

Nintendo obviously for number of successful exclusives of course. Their core franchises sell more and are carefully maintained.

I'll give Sony a decent second place nod for pushing the most new IP though - they delivered more new IP to try out this gen than anyone else IMHO. MS trail behind a fair but their focus is a small number of core exclusives (Halo, Gears, Fable and Forza really at this point) with a focus on third party timed exclusives and timed exclusive DLC.

Of course Kinect seems to be where MS are investing more in exclusives and new IP so that line of titles may bring them closer to Nintedo/Sony.
