although it probably wont happen, itd be interesting to even see Sora interact with Roxas and Xion somehow, since Xion says "lets meet again" in the end. In terms of using Roxas, maybe there is a new way to summon him, and since he did have other powers that Sora did not have, I would still think theyre somewhat two entities even though theyre supposed to be one (unless Sora gains Roxas's other abilities in KH3). Maybe Roxas himself is a drive form, since he can dual-wield. Or maybe this drive form can either turn Sora into Roxas (75% chance) or into Xion (25% chance).. @_@ sorta like an identity switch, since Roxas can see through Sora's eyes, why not Sora seeing through Roxas's eyes? .....
