Last year, Capcom USA said they were working on getting Capcom vs. SNK 2 onto the PlayStation Network as a PS2 Classic. That might be happening sooner than you would imagine.
Over on the Capcom forums, a user asked for an update on the status of Capcom vs. SNK 2 on the North American PlayStation Store. Capcom USA’s Senior Vice-President Christian Svensson replied: “Current schedule for the release of the PS2 game is the end of April… mind you, if Sony chooses, that could move (it is later than I had originally anticipated already).”
So, provided there aren’t any hiccups along the way, it shouldn’t be long now.
