As long as it's still in the earlier part of 2012 (as in January) I'm okay with that. Even if it does mean I have to spend an extra few months not hearing anything about the plot or characters of ME3.
I don't even know why Cerberus are doing whatever it is they're doing this time around. I tend to keep it that way until I get the game.
It's a challenge though: think I can make it all the way to release without knowing anything about plot, setting, squadmates or well, anything about the game whatsoever? That is the plan.
