That is interesting because, if you notice, they introduced both those songs only on numbered titles and just reused them all on the other games. Considering that they will be returning to the (More evolved) default system I think there is a high chance of a new song as well. REJOICE!

On the pixar and star wars; totally. As for marvel, I think it would be kinda okay if they didn't try to go to fast: It was previously seperate from Disney as was Lucas arts so they will be somewhat different in terms of just how exactly they would work without ruining the in-game versions of those characters. For star wars it shouldn't be too hard, but marvel..... it's very different. ( No random singing on a regular basis for one thing)

I nearly forgot about that....

Over all on the comments about clothes:
I didn't hate his first outfit too much. They were trying to be reminiscent of Mickey after all. When they used it a few extra times, that was okay. Limit Form? Fine. It actually is improved version of the original. Not quite as balloon-y and over sized. 2 time was fine, limit form was okay. then... well this:

Last but not least:

THEY'D BETTER NOT TRASH THEM!
Seriously though: since the emulation of what we are supposed to be getting "Eventually" for 3 had a drive gauge, I imagine it would serve some purpose.

Overall, I just hope they take the new game mechanics they have been shoving down our throats, and artfully combine them with the KH system to make a Wonderfully EPIC game that perfectly expresses; KINGDOM HEARTS

It would be great if there was TOY STORY'S WORLD and Buzz lightyear cartoon's world, just like there was a "Tron world" and the "Space paranoids" world... maybe we could have some conection with Buzz beforehand like he remember us even without knowing us, just like Leon at Castle Oblivion.

To be honest i don't want Sora to get a different outfit, he appears in black only in KHII. O well as long as it looks as good as that i'm in.
