Ok if you want to see this be my guest but if you want to defeat KH2 before you see the secret ending clip (sorry if that a spolier) Then I dont highly suggest it. The first clip is the KH2 secret ending, the second clip is from Kingdom Hearts-Final Mix
The guy that did this said his opinions and other things. He, in my opinon, is very accurate about whats going to happen in KH3. And yes, that is Mickey. I think Disney was going to sue Squaresoft (yeah i forgot the name of the company, forgive me) if they didnt put at least one of there characters in the trailer. rolleyesxdwhee
