Mass Effect is not tied up on a 1st Party contract, contrary to what you have been lead to believe. Where were you during the talk of Mass Effect "maybe" coming to PS3? You think a 1st Party title could even be in question?
I was making a point though. Those were wildcard examples to begin with, but they got the message across.
What talk? Can you link me, because all I've seen is unsubstantiated speculation based on a few lines of code, some crazy Pachter talk and the usual PR "no comment" from EA/Bioware? All that's been confirmed is that Microsoft had an exclusivity agreement for the first trilogy before the EA buyout, and no one would comment on if/how the terms of that might've changed post-buyout... if I'm wrong on all this, feel free to source me.
And the "point" seemed misplaced given you bought 1st party product dealings into it (which Versus and Conviction certainly aren't). It's about as legitimate as bringing up the notion of Heavy Rain or the Pixeljunk series on 360. It seems a bit irrelevant and inflammatory.
