Will it hold against CoD? No. It will however still have its own smaller audience, like Halo.
...No it won't...
Well, that's to say, it won't compared to the Halos released so far. The ones that aren't made by Bungie that have yet to be announced? Well... we'll see.
lol, how long has Halo been out? It was a launch title for the original xbox.
How long has Brink been out? How long has SD developed games for console?
So a brand new IP developed by a PC company, who up until now, has never developed a game for console, may not have a following as a big as a franchise that has had over a decade to obtain fans? Say it ain't so....
He's simply saying Brink doesn't stand a chance against Microsoft's juggernaut, which it doesn't. Your point is moot because it is irrelevant.
Besides, since we're gonna go back to the original Halo's release, Halo: Combat Evolved debuted and was hailed as the best First Person Shooter... ever, and redefined the entire genre. In Brink I'm pretty sure you'll be carrying two weapons at a time and be moving with one stick and looking around with another. It got to the point that people were making games JUST to beat Halo and the term thought up for it was "Halo Killer", with the only shooter so far able to actually earn that title being Call of Duty.
Just Sayin'.
