Man, Capcom is really running that well dry. Remasters for the REmake, Zero, 6, and now 2 and 5 on the way.
Anyway, for those interested in playing RE5, I would certainly recommend doing so with a friend. It's one of the better co-op experiences from last gen. If you're an RE purist, you might be turned off by the focus on action and absence of horror, but as a third person shooter RE5 is a lot of fun.
