As far as Sora duel-wielding, that's only if he's in a Drive form other than Wisdom or Anti. Most likely he'd start out with just the Kingdom Key. Then of course Riku and Kairi would have Way to the Dawn and...whatever that one with the Destiny Islands motif was called.

They found/reunited with their true selves and each other, a bit too much of a happy ending for Disney to want to spoil, I'd think.
So really, I think they'd just be starting with, at most, 3....4 if you count Mickey's, as Shaun called it, Magic Kingdom Key.
