For once, I kind of have to side with Morari on this. While this move makes me more optimistic for the future of the Lucasfilm properties than I have been in a decade, I am concerned that Disney keeps eating up all these major companies. It's like how Square-Enix now seems to comprise nearly the entire non-Nintendo Japanese game industry these days, and as a result there are all these smaller franchises that have just been buried for the sake of Final Fantasy.
I don't mind big companies existing, and this acquisition could lead to some very cool things (hey, between Marvel and Star Wars, Kingdom Hearts now has a healthy stock of new worlds to exploit). At the same thing, though, I don't like seeing seemingly everything consolidated into a few noteworthy companies.
