Definitely would like to see an older female combatant. I think the only game that had one was Power Instinct? The one who could turn young by kissing you. I think she even had an evil twin sister in a green gi for a sequel?
-I’d love to see the SF2 style continue screen and win/loss portraits make a return.
-Bring on the flags!
-A mix between new and old bonus stages. It would be kind of cool to get a mode were you could mess around with them after a few playthroughs!
-I know some people don’t like unlocking characters, but I would like to see extras to be unlocked. Character model viewer along with a streamlined character/event encyclopedia, bonus round mini-game mode as mentioned above, remixed tracks similar to the way Soul Blade/Edge had Khan Super Session as well as original and remixed. Concept art, rejected designs, general promotional and extra art (like in SFA2) alongside a theatre mode.

A character with rekka fireballs.
A Sonny Chiba character to finally tie the franchise with the original Street Fighter movie:

A character that focuses on the ice element. Everyone and his mom can set people on fire in SF, and ice could look awesome with the improved graphics. Extra points if after a KO with an ice move, the character stays still instead of falling to the ground.

Oh yeah: a big array of symbols to mark round wins like Alpha. I’m going to miss the cheese symbol, though. :\

It will have also awesome moveset potential, more strategic than damage oriented
I will like a not-scifi version of her

What if Sean turned into the “ice” shoto? That’d be an interesting twist.
Also, I want divekicks (if there’s any) to bounce off on block.

Actually, I hope that he’s in and he’s given the USFIV DeeJay treatment.

Gill is half Ice, if he’s in we’re in for a visual treat to say the least as they translate his godliness into the new engine.
An ice fighter could fit it though if he/she are technological, like Viper, Seth or Doctrine Dark. Or if they are members of the Illuminati who have been established to have secret techniques in lore.
But in general, if we start introducing more “magic” and mysticism, we will push the SF power levels into MK territory. The introduction of Gill and then Ingrid already stretched it out.
Now we have Akuma who was a metaphorical demon but now is quite possibly gonna turn into a real demon.
Bison whose psychic powers can suddenly tear open wormholes in space and time, not to mention that he is no longer human as well (demon like Akuma probably).
But i’m fine with these because they are the boss characters.
Also what is it with you people thinking this is Bison’s ‘swan song’! He isn’t gonna die this game or any game! BISON IS 4EVER!
@Cestus
I totally agree with you about Seth. Had he been clothed, he would’ve stood out much better. Considering that he thought himself unique, it would’ve made sense if he was clothed.
What they could have done is kept him clothed by have his clothes rip apart as the fight goes on, revealing his cybernetic implants slowly. That would’ve been epic.
