Since Roxas joined with Sora and "completed" him, I think it only be appropriate if Roxas returned in flashbacks.
See, they kind of messed up story. KHII was his only time to really be a character, and have a story of his own. So now that he fused with Sora, it would be impossible for him to make a return unless they were flashbacks, so he can't really come back in KHIII. Although, I would like him to come back. Having him as a summon or a drive form is a good idea too.
