Why do X360 exclusives sell more than PS3 exclusives?

[Corey]

First of all a few of those aren't exclusives on the xbox side, the are also on PC which is in fact relevant.

And kinectimals, can you really count that? It was a bundled title with every Kinect. It would be like counting wiisports.

I think after factoring in the above the numbers it would be a bit more even.
