As long as the game is solid I am fine with it coming out soon. I don't know if you like the Assassin's Creed games, but they have been coming out almost yearly. I really enjoy the series so I am looking forward to what the story holds in each new game.
I agree that some games loose their appeal when sequels just keep on popping up, but this is more of a concern for multiplayer games. I would be happy if Mass Effect 3 came out six months after ME2, just so I can continue the story......but I don't need or want another Halo/CoD/Skate, at least for a while.
It's hard to have too much anticipation for new IP's because you just don't know what you're going to get. I like to follow development teams. The Last Guardian isn't necessarily a sequel, but because of Ico and Shadow of the Colossus, I'm pretty much all in.
I am excited about Brink as well.
I think it accomplishes what I EA set out to do which is dumb down football for casual gamers and cut the game time down. To me, a lot of the fun of Madden is the strategy involved in picking out the right play for the given situation, especially in PvP. Gameflow throws that out the window. Plus, defensively, its all about knowing each players responsibilities. Using GameFlow, you don't have enough time to assess which defense was called. I will admit that having the coach yell at you for giving up a 7 yard run on 1st down is pretty rad.
