Daigo Umehara's Impressions of SSF4 AE
• Fireball characters are considerably weaker in this version.
• He thinks Yun will be really good, though Zangief will be a tough matchup for him. Hasn't played much Yang, but thinks that his Genei Jin (Super) will be a big difference between the two characters.
• Even though Fei Long lost the invincibility on his Hard Kick Chicken Wing, with better normal moves and all the tools he still has available (Rekka, Tenshin, etc.), and Chun-Li, Honda, and Balrog getting nerfs, he says that Fei Long is probably the strongest of the old characters in Arcade Edition.
• Daigo feels Yun, Yang and Fei Long will be top class in SSF4 AE. After these people he ranked Zangief, Balrog and C. Viper next.
• He thinks Ken will be stronger than Ryu and Akuma, though they're still upper tier.
• Balrog will be a tough matchup for both Yun and Yang, since they don't have a punish for Dash Straight, and he has his Crouching Hard Punch.
• Makoto is stronger than he thought she would be.
• With the nerfs, he puts Guile at upper-mid tier, and he'll probably keep him around as a secondary character.
• He really seems to fear the Zangief matchup with Yun.
• With the EX Green Hand changes, Sagat will have a favorable matchup against Zangief. Puts Sagat at the bottom of the upper tier.
• Many of Daigo's impression revolve around if said characters can beat Zangief.
• Apparently, Dhalsim's Standing Light Kick is slower.
• Ryu's Light Punch Shoryuken can trade into Ultra.
