« New Super Street Fighter 4 Dev Blog Details Changes for Arcade Edition: Ken, Vega, Rufus, Fei-Long and Juri »
The new Super Street Fighter 4 development blog details upcoming changes for a handful of the roster in the arcade edition of the game. This blog goes over Ken, Vega, Rufus, Fei-Long and Juri. Below is a compilation of translations for each character, and we will continue to update this post as more emerge. Thanks to USD from NeoGAF for this initial write-up.
Be sure to sound off in the comments and let us know what you think about the upcoming changes!
KEN
USD Translation:
Normals
-Less recovery on cr.MP, can now combo cr.MP into cr.MK
-Improved hit box for cl.LP and target combo (assuming this to mean more range)
Special
- LP Shoryu has 2 extra frames of recovery, but does 120 damage
- EX Hado can juggle twice in the air, so you can get full juggle off LP Shoryu > EX Hado
- EX Air Tatsu is no longer an overhead
Other
- Is considered to be mid-air right after the invincibility frames of his backdash end
VEGA
USD Translation:
Normals
- cr.MK start up is now 6 frames (2 frames faster)
- Less damage on cr.MP and cr.HK
Unique Attacks
- More recovery for Cosmic Heel on block
Specials
- Less recovery on EX roll
- You can now combo cr.MP from EX roll
Ultra
- U2 has slightly more startup
Other
- Is considered to be mid-air right after the invincibility frames of his backdash end
RUFUS
USD Translation:
Specials
- Anti-air U2 does not give you the full hits
- EX Messiah does less damage (80 PTS of Damage)
Other
Is considered to be mid-air right after the invincibility frames of his backdash end
FEI-LONG
USD Translation:
Normals
- Close and Far stand jab are have an extra frame of advantage (now +6)

Specials

USD Translation:
Specials

Ultra
No changes to U1, but because of the changes to the charge kick, it's easier to score knockdowns

Improvements to hitbox, EX FA (Not sure about this one, take with a grain of salt)
Next Week's Update: Chun-Li, El Fuerte, Sakura and Cody.

Street11 on SRK translated some of the more releveant Q&A's from the Dev Blog as well. Check 'em out below!
Q: I have a question about Guys changes. How should I take your post about super armor? Is it okay if I take it as "focus 1 hit"?
A: Like you said, it can focus 1 hit. Since EX Run can focus 2 hits to begin with, you can now focus all of Akuma's HP Shakunetsu Hadouken by timing your EX Run -> Stop. Of course, you'll take gray damage.
Q: Is there no changes to Viper's U1 damage? It has a lot of ways to combo into, and its damage seems to be too high.
A: There's no change to Viper's U1
Q: About Ryu's LP SRK, would he be now grounded when meatied, or will he still take airborne damage?
A: Ryu's LP SRK has now 1~3f as grounded, and 4f~to the ground as airborne. Therefore, there would be situations where trade LP SRK -> Metsu Hadouken is possible.
Q: About Cammy's changes, I want to know about Cannon Strike's height restriction. Also, I want to know if there are any changes to SA, Spin Knuckle, and Hooligan.
A: To explain Cannon Strike's height restriction, it means that there's a certain height where the game will register the command for Cannon Strike. It doesn't matter which point of the jump, the command will not register if the character is not above the certain height. There was a change to each of LK, MK, and HK SA, and we also adjusted HK SA's active frame distribution (<- since HK SA is 2 hits, maybe they'll shorten the first hit then lengthen the second hit, or vice versa). There are no changes to Knuckle and Hooligan
Q: OMFG BOXER HAS NERFS ONLY
A: Live with itOk, the last Q&A wasn't directly translated (in fact they sound much much more polite and explains how he became more technical), but that's how it basically looked like to me.
