We suppose some people will be upset about it but considering the GSB team expects the co-op to be added soon after release, Microsoft hopes for an update within a week or release, we aren't freaking out yet. However, considering most reviews will take the omission into account we wouldn't be surprised to see Fable 2 take a few dings on the Metacritic front. If that means anything to you, at all.
