A look at 2007 Third Party Exclusives...

TheSource said: There is actually almost nothing 3rd party that is exclusive and real significant... Halo 3, Lost Odyssey, Mass Effect, Shadow Run, Too Human, Blue Dragon are all published by Microsoft.

Published by, sure, but it's not like Mass Effect is really a first-party title. Bioware was going to make Mass Effect whether or not Microsoft published it, and could have done it Bethesda-style with a cross-platform release. That Microsoft is publishing it on the 360 rather than just paying them to publish it themselves as a third-party exclusive isn't a particularly huge distinction.
