KH2 certainly looks great. I'm giving it the benefit of the doubt, despite hating the first for several reasons. If they fix those, it might be worth getting since I'm a big Disney fan.
I hope there is a Lion King level as well. Simba was a summon in the first game, so I don't see why not. I always found it odd that Mushu was a summon but there was no Mulan world. I'm very glad they put Mulan in KHII. She is going to kick ass!
