wow, I always thought WOW was such a big cash cow that it pretty much funded all of activision. (well that and the COD franchise)
I must say though, much like EA a number of years** ago they have been peddling the same old game with a new skin for so long now that some sort of shake up may be a good thing.
**Maybe it is my imagination but I do feel that EA do seem to put more effort into even their yearly franchises these days.
