Also Online Only is much more niche than a game like L4D.
L4D can be played by 37Million 360 owners around the world.
MAG can be played by 24M? I believe 24M is the last known PSN number Sony released. Then let us agree like many said, that many of those are PC accounts, PSP accounts and duplicate PS3 accounts. We agree that maybe half the PS3 userbase is able to play MAG?
Anyways, as for the topic on hand I don't think Mass Effect will eat up MAG sales, just as I don't think Splinter Cell will eat up Heavy Rain sales. They are all different genres on different consoles.
iPhone = Great gaming device. Don't agree? Who cares, because you're wrong.
