I'm actually looking forward to how the new Tangled world would turn out. Though I kinda knew that Tangled would be the next new world in the KH franchise.
Anyway, I'm still hoping they'll add Agrabah one more time for it's last story line "Aladdin and the King of Thieves" since that's the last film of Aladdin's own trilogy, and what a bummer would it be if they don't include the last storyline installment of that in KH3, right? They made a similiar storyline to "The Return of Jafar" in KH2.
And they better bring back the Final Fantasy characters that appeared in both KH1 and KH2-Leon, Yuffie, Aerith, Cid, Cloud, Tifa and Sephiroth-and add Rinoa, Zell, Vincent, and maybe Reno to act as Lea's brother or something(that would be awesome!) with the other Turks and maybe Bravely Default characters-Tiz and Anges.
Just wish they kept Sora in his KH2 clothes and hair-style. You only got one game of Sora in his KH2 clothes in a gameplay and cutscenes which was KH2 itself. The rest of the titles mostly have Sora in his KH1 clothes in gameplays, while Sora in his KH2 clothes only appear in the cutscenes of KH BBS and KH 3D, which sucks. Sure you get to play as him in his KH2 outfit for a short time in KH3, but they should've let him stay in those clothes.
But no, Nomura had to be stupid and listen to the staff members instead of going for what the fans would like since Sora's KH2 outfit is more popular, according to him, and he was actually torn by this, which, in the end, made him go and listen to the staff and we have Sora in his new KH3 outfit and that stupid new hair-cut.
I don't know if any of you played Chaos Rings 3, but if you look closely to Nasca(the main protagonist in Chaos Rings 3) and Sora's new outfit, the new outfit looks like a replica of Nasca's outfit(which is extremely similiar since it's red and he has black gloves just like Sora).
