That frozen dude looks like Roxas, VERY MUCH, So, if that's not Roxas, then who is it?! Cause I'm like 100% sure that, thats Roxas! and if its not, someone please tell me
The frozen dude looks like roxas, and the guy at the end looks like Axel, but the blue haired girl/guy(think its a girl) I dunno who is, BUT!
Maybe the red haired guy IS Axel before he got turned into a nobody and all these stuff took place before KH 1 and 2
And as the producer said, the 3 armored figures were new characters, but that doesn't mean that old characters like "Roxas" still aren't in the game right?
JUST THINKING OUT LOUD! xD
