Yeah, I have to say it's certainly not as dark as I expected, but it's still pretty heavy for a Disney game. I was sort of hoping that Oswald was a villain at first, but just wanted a rather meager goal and ended up being used by Phantom Blot who wanted control over everything. Hopefully there's more to it than that, but I guess we'll have to wait and see.
I'm thinking there's a good chance of seeing this game sometime in Jan. 2011; just from the screenshots alone it seems like a [parasitic bomb]-ton of stuff was done in between the leak and now, so we can probably expect them to keep working through E3, put up a teaser/trailer for it by then, and then announce the release date past July.
