All they need to do for FFXV is have some Kingdom Hearts poster/figure/two kids that vaguely resemble Sora and Riku running around in some town. I'd rather not fight Sora in FFXV of all things.
As for Noctis in KH3, I'd rather it'd be bb!Noctis to represent how he is technically the "younger brother" in Nomura's mind.
No to 5 (unless it is Big Hero 6) & 8 lol I'm sorry but Square Enix can't do live action commercials for crap. I still cringe at the FFXIV one, and the LRFF one was mostly CG rofl.
Everything else I'm cool with (except that one line about Ven and Sora wielding. NO VEN IS NOT THE REASON SORA CAN WIELD HE EARNED THE KEYBLADE ON HIS OWN THANK YOU VERY MUCH)
