Okay, here we go:
Likes:
-The cast of TWEWY in Traverse Town
-The Dream Eaters (being enemies and allies)
-Notré Dame and Tron: Legacy
-The costume changes
-The return of the Command Deck
Dislikes:
-Umm, I actually don't have any direct dislikes... just fears.
Hopes:
-A return to the platforming and area design seen in KH1 (we've seen a bit of a return in BbS)
-Keyblades returning to the strength they had in KH1 only with the abilities from KH2
-Keyblades for Riku
-A synthesis system
-A balance between BbS and Re:coded in the Commend system (melding and leveling up)
-For Dream Eaters (as party members) to increase in usefulness beyond just being used for combo attacks or support
-A secret boss or two (Dream Eaters as bosses are fine in my book)
-Chests that aren't out in the open... and DISAPPEAR after opening them (Is there ANY reason they don't anymore? <x[)
-The return of ALL former Org. members, for better of for worse
-A return of the Dream Sword, Shield, and Rod level system (with level up speed determined by Dawn, Day, or Night like in KH1)
-Final Fantasy Characters! New ones!
-A Radiant Garden that's not just a bunch of town areas (more castle exploration)
-A return of a more mature Sora (No KH2 Sora please)
Fears:
-The further downplay of party members' usefulness
-I'd rather the acrobatic play STAY in 3D and not make any moves to KH3
-Further convulsion of the story (of course)
-A lack of a Olympus Coliseum stand-in
-That worlds like Notré Dame may not appear in full glory in KH3 (with Quasimoto not being a full-fledged party member and such)
-A low average end game level like BbS (30? Please bump it back to 50? <x[)
-The "Ultima Weapon" wont be an ultimate weapon (ie having Keyblades that are stronger than it, two the excel in Magic and Attack, like Diamond Dust and One-Winged Angel, is okay)
-That it'll be too short <x[
