Unfortunately, I don't think it's too popular. I mean, I just learned of this game from a small blurb in Game Informer---but also mostly because it's on Bethesda's list of game forums. (I play Elder Scrolls games and there's new Beth. games called Skyrim and Rage coming out, so that was why I would be there). If it wasn't for that, I don't think I would have known about the existence of this game. -_-
Also, there are other games/sequels of well-known developers or favorite series that are coming out this year that are showing new info and getting more publicity: Killzone 3, Rage, Uncharted 3, Arkham Asylum, Skyrim, Mass Effect 3, Deus Ex, some other shooters and RPGs, etc.
I think it needs to be advertised a little more or, at the very least, show up on the radar with new news and info or game footage... Something to remind people this game is still existing.
However, I think maybe they will show the game more as May comes closer, so here's hoping to that.
I just pray it doesn't get lost in the sea of shooters (especially first-person shooters which are becoming more and more common)!
