I posted this on the SRK forums about a week or so ago, but I suppose it would be good to post it here too. So this month's issue of Arcadia (released in Dec, marked Jan, has DVD included for those who want it) includes a special for SFIV where they held a kumite between Daigo and six of the top players in the country from different games. The people that they chose are:

Nemo: Guilty Gear, KOF player (65K BP with Chun)
JOE: VF player and SBO '08 winner, uses C. Viper (56K) and is ranked in the top 10.
Inoue: Cvs2, etc, etc. (32K BP)
Fuudo: VF player, first VF5 national champ and SBO '08 winner with JOE (43K BP)
Itabashi Zangief: Well known VF player (35K BP)
Mago: CvS, CFJ, etc. Top 3 in SF4 ranking. (73K BP)

Here are the results of the Kumite.

Umehara vs Inoue: 2 - 1
Umehara vs. Itabashi Zangief: 3 - 0
Umehara vs. Fuudo: 3 - 0
Umehara vs. Joe: 2 - 1
Umehara vs. Nemo: 3 - 0
Umehara vs. Mago: 1 - 3

Umehara: 14 wins, 4 losses

The DVD shows some of the matches plus commentary from Umehara and his opponents, but unfortunately putting this up on YouTube would be mean copyright infringement, so if you're interested in watching some high-quality vids of Daigo playing, I'd suggest you guys go out and get the magazine if you can!
