I was checking out the PSN update for this week and I find this game at the bottom as the PSone Japan import.  I know the game came to the US as an arcade release, but I don't think any of the home console ports were released outside of Japan.  You would most likely know the game from the characters who have been in crossovers.  Jin was in Marvel vs. Capcom 2 and Devilot was in Super Puzzle Fighter II Turbo.  
 
As with the release of the PS1 version of Street Fighter Alpha 3 on PSN, the excitement over the news is dampened by the lack of online multiplayer.  However, I am still quite excited to pick this game up and see how it plays.  Coupled with the appearance of a Cyberbot in a Street Fighter X Tekken background, I have to wonder if Capcom has some additional plans for this game.

Great! Too bad the ps1 versions of all those games were the gimpy ones.....
