Hiya, long long time SC player here.
One thing that I've been yearning for since SC1 is for each character to be voice acted in his or her native language. Seigfried & Hilde should speak German, Mina and Hwang (Please bring him back) Korean, Xiang and Li Long (Bring him back too) Chinese, Astaroth uhhh?, Cervantes Spanish, etc. I understand having all of them speak English, since basically every video game ever does the same thing for foreign characters, but, in the US anyway, having them all speak Japanese sounds super weird, unless you're an anime fanboy I guess. And either option really destroys my suspension of disbelief (If surviving a hit from a 6 foot long sword hadn't already, but you know). Soul Blade almost had it right, with Western characters speaking English, and Asians speaking Japanese, but then, instead of getting it totally right the next game, they stepped in the opposite direction and now we have this.
Speaking of character nationalities... Okay, Hilde and Seig look very German, excellent. I can believe Amy and Raph are French, good. Rock and Ivy look like they could be British (Even though Ivy is supposed to be at least half Spanish, but okay, she's plausibly that too), but Xiang SURE don't look Chinese, Taki looks more like Megan Fox with those blue eyes than she looks Japanese, Hwang/Yunsung look like some kind of New Jersey guidos, Mina Korean, Talim pinay? Please... and the sisters look more Swedish than Greek. Okay, the sisters can't really be changed without totally re-inventing their whole look, but PLEASE at least make Asian characters look Asian. I don't know WTF kind of problem Japanese have with their own self image, but they must really hate the way they look, because every Asian female in every game I've ever seen has a rare genetic mutation to make her look like she came from South Carolina. SC3 had Taki looking pretty good. (

The next thing I'd like to see is a much better online lobby. I can't tell you how frustrating it was to play "Join game session," "The game session is full," "Join game session," "The game session is full," "Join game session," "The game session is full," "Join game session," "The game session is full," "Join game session," "The game session is full," ten times in a row. If the game session is full, then don't f-ing show it to me as a joinable session.
Also, I hear MK9 is going to have a "spectator mode" where you can watch other people fighting and make comments and give "respect points." That's a spectacular idea and would really liven up the online community.
Some other game, I forget which, [edit: Oh, MVC3], has a hidden code for detecting people who constantly disconnect when losing. Then, instead of doing something ineffective like displaying a "bad disconnector rating," the game keeps the fact invisible, but starts pairing them up more and more with other people who also disconnect. That is an ULTRA-spectacular idea, and would probably just about solve the problem of pullers.
And please, NO GIMMICK CHARACTERS. I know you want every Starwars/Spawn/Zelda/HarryPotter/Sex&TheCity fan to buy Soul Calibur, but let's make them want to play based on the game's great story and awesome mechanics, not on a cheap shoehorned-in gimmick character. Please?
Let us edit ALL of the color on the main costume of the characters in Character Creation. Cause i dont like that red bead on Talim's necklace when the rest of her outfit is purple and blue.
THIS. I hated having that big yellow flower on talim's 2p shirt. Most of the other outfits weren't guilty of this though, thankfully.
And speaking of custom characters, please let us modify facial features instead of just giving us 8 default faces of which 3 are decent and the rest are varying degrees of ugly. That guy that posted the Eve Online custom character video had it right. And again, please give us some ASIAN eyes. Not all of us hate the way you look as much as you hate yourselves, Japanese people. Srsly.
Those are my ideas.
