It's been over a decade, it WILL fail. They hype it has to live up to is extremely unreasonable. My final sentece shall be as such. Good bye Gearbox, I was hoping for another Borderlands but now that you will be going under, I guess Borderlands 2 will never exsist.
I think the hype actually hit full circle. By this point, there's not really an expectation that it's going to be amazing, but just curiosity that it took this long to come out.
Plus, after so many realistic military shooters (Call Of Duty, Metal Of Honor) and slightly less realistic sci-fi military shooters (Halo, Half-Life), you have Duke Nukem and Bulletstorm promising to go in the opposite direction with over-the-top action and humor. If the games are both quality, maybe there's a chance for a new trend to emerge out of this.
But back to the OP. Assuming the game is good, I think it will be a solid hit. If the reviewers are really in the mood for this sort of game and it gets amazing reviews, it could actually be a pretty damn big hit. This game is going to have a lot of eyes on it simply because it's been an Internet joke for so long, so reviews and word of mouth (good or bad) are going to have a big influence.
