Mass Effect 2 and Bioshock 2: Will Microsoft buy them?

[WiiStation360]

I think Bioshock sales prove that long term exclusivity kills sales on other systems. This will make it even harder to Sony/MS to buy 1 year exclusivity.

I would expect more 1-2 month exclusivity deals, (like Rockband2) or exclusive DLC (Fallout3 or GTA4).
