SMOAI2010 has posted four videos of a recent Japanese online UMVC3 tournament. The videos are each around twenty minutes long and consist of several matches each. You can see some really high level play, including interesting surprises such as a deadly Phoenix Wright team post nerf, some skillful play of Tron and Haggar on point, and even a few new tricks with Thor. One character you didn’t see all that much was Wesker, though Dr. Doom certainly got more than enough time in the spotlight.
