I'm actually kind of tired about the whole "Zombie" fad\genre. I don't really like playing Zombies on Black Ops. I bought Undead Nightmare for RDR, but I only played it for about an hour, then quit. When the PS Network came back up and they were giving out the free games, I got Dead Nation, but got sick of it after 10 minutes. The only thing "zombie" related that I really enjoyed recently was the movie Zombieland, only because it was hilarious. (Oh, and White Zombie! Rob Zombie.....not as much.) But I think the entertainment industry has really overdone it with the whole zombie genre. So no, I have discernible interest in anything else zombie related.
I'd rather spend $120 to buy MW3 & BF3, than any other game coming out around the same time. Plus, if Dead Island comes out anytime near Gears of War 3, then it doesn't even exist to me.
