[Vermilion Thanatos]

Yes, it is obviously KH-style Moogle. In other forums I've seen speculation that the summons are now 3D, but that sounds like a pointless endeavor. And, in jest, he might be the announcer-- "FINISH HIM, kupo."

But the problem is, I don't understand the whole cameo bit. We know that we'll be getting a few more menu cameos, but I'm pretty sure those are 2D. And there's no point in adding a few NPCs to story mode, which I'm sure everyone will agree with once they play it. And I can't see it as a playable character because we've already got a Taru--and I can't think of what the Moogle would do in battle.

Which leads me to believe that maybe this implies a Sora secret character...though I can think of at least a dozen FF characters that deserved it more.
