The Return of Telekinesis (Final Form)

[Fullmetal Keyblade 88]

Given how Final Form was essentially a "All Your Powers Combined" ability in KH2 and represents Sora's completion, I believe that KH3 will have something similar occur, albeit in a grander and stronger version. It would be incredible for example to see Sora utilize several Keyblades at once, perhaps even transforming multiple Keyblades at the same time. Although I admit that sounds a bit unpractical if not down right improbable, I still can't help but think that something like this is bound to occur as we have not (nor likely will not) see the full extent of Sora's strength until the game's release. Please let me know what you all think!

I'm hoping it's one of those Special Forms specific to a Keyblade. Hopefully it's exclusive to the Ultima.

This definitely resembles Final Form but it's also different. It's probably KH3's version of it, but it may be something else entirely.
