So we know that everyone is going to get an alternate outfit for Dissidia 012 and we've already confirmed Lightning's three outfits for sure and possibly Cloud's unless they decide to switch out his AC outfit or if the DLC/Code outfits they are both getting doesn't count towards the three outfit limit.

Without getting too far into weird speculation, what are your guesses for the rest of the casts alternate outfits?
Emperor Mateus ~ One more faithfully based off his CG build from Origins.

Onion Knight ~ Ingus' OK outfit and hair.

Cecil ~ After Years outfit

Kain ~ (SPOILER)Hooded Man from After Years

Bartz ~ Outfit based off his SNES sprite

Terra ~ Outfit based off Celes' outfit since I highly doubt they would choose
Celes over Locke unless Kitase meddles.

Kefka ~ They will probably be boring and base it off another Amano piece (he is literally in a different outfit for every piece of artwork he's in), most likely the green one that his sprite seems to be based off.

Sephiroth ~ If they are boring, his KH outfit *shudders* if they want to be risque... Genesis' outfit, if they want to be really interesting, I would love to see Sephiroth in a standard SOLDIER uniform.

Squall ~ if they want to be boring, give him his Balamb Garden Uniform or one of his KH outfits. If they want to be clever, give him Laguna's Outfit.

Ultimecia - Edea's Outfit if only because it's character model isn't a huge stretch from the one Ultimecia already uses.

Zidane and Kuja ~ Just to be really fun, have them switch outfits

Tidus ~ Looking at some of the videos, Tidus has a new outfit in the Full CG video, which looks like his own version of Jecht's outfit. Otherwise give him Shuyin's outfit.

Jecht ~ If I can't have Auron at least let Jecht dress like him.

Shantatto ~ XI Red Mage baby

Gabranth ~ I want his outfit from the ending credits in XII
