Broski, hate to be the dream-crusher here but the heart and soul of Rare left a while back (literally, a few of the guys that basically made Rare "Rare" left Microsoft).
Don't be shocked if we never see anything out of them that matches their previous glory.
Didn't those "heart and soul of Rare" guys make an underwhelming XBLA game? Plus if there are a lot of new people, can't they also make great games? See Playground - their first game was fantastic. I often don't get those posts.
