Here's a video of Japanese Street Fighter players (including Otochun and Aniken) playing SF HD Remix. Skip to about 1:05:00 or so for when they finally get going.
They are having such a good time that it makes even more fun to watch. They all laugh (in happiness I think!) when Vega's wall dive doesn't knock down, and when someone lands a fake slide into throw with Bison. They also get excited that Ken can now do his super as a reversal.
With Daigo and Tokido both saying good things about the game, Muteki, Yuu Vega, and Jodim all playing on XBLA, and videos like this one, it seems they are pretty into it. Aniken said this (to Masa) in the comment thread about an HD Remix event there:
I also think it would be interesting and fun to have HD at the game center
but we have to face reality, there's nothing we can do about it!
For Ken, Remix Ryu and Sagat are very difficult opponents, it's fun!♪
Looking forward to seeing you at Sunday's tourney!
Too bad the game isn't actually released in Japan, it seems like it would do really well.
