Just wanted to clear up a few things. Yun and Yang were released on SSF4: Arcade Edition, in a attempt to get players back into whatever arcades still exist around here. I know of one in Moorpark/Simi which is about a half hour away from me, but I'm sure it's probably much worse for some of you guys. Not talkin about a pizza place with a Tekken Tag machine, I'm talking about a real fullblown arcade-and-nothing-but place. The kind where Third Strike tournaments are still held. In addition to the kung fu twins, there's two more characters who are fightable through still-unknown-or-unreleased secret means. They are Evil Ryu and ???? Akuma. Believed to be Shin Akuma (the souped-up one from Alpha), but I can't find a definite source or video. Presumably they will have different or altered moves, Evil Ryu had Akuma's teleport and Demon, hopefully it will be more than that, I hope ???? Akuma loses the fucking retarded second ultra he has. Us console owners will have to wait apparently six months to download "Arcade Edition" into our pre existing SSF4 data. Won't do me much good, but I'll check it out next year or so probably.
I also dug up a tier list in case anyone was curious.
Top: Honda, Bison, Guile, Chun
High: Balrog, Cammy, Ryu, Abel, Dhalsim, Rufus, Sagat, Seth
Mid: Akuma, Fei Long, Ken, Rose, Blanka, Zangief, Dee Jay, Adon
Low: Ibuki, Vega, Cody, C.Viper, Fuerte, Dudley, Gouken, Juri, Sakura
Bottom: Guy, Gen, Dan, Hakan, Makoto
Unplaced: T.Hawk (either he's really good or really bad vs. some people, data pending)
Goes without saying that Arcade Edition will shake this up pretty good, so this is SSF4 only. Some characters, like Hakan, Makoto, Gouken and Dudley have already been stated to have recieved move-property improvements.
