Famitsu Weekly reports that Street Fighter III: Third Strike is on its way to PlayStation 2 later this year, and that Capcom is currently considering whether or not to offer online options. Although Third Strike (not to be confused with Double Impact) was originally released on the Dreamcast back in 2000, huge lapses don't often stop Capcom porting games with older tech - just look to Resident Evil 2, 3 and Code: Veronica on GameCube if you want some current examples.
Meanwhile the question of online support is certainly bound to dominate discussion of the subject. Capcom has dabbled with PS2 Online in Japan several times, even with a beat-'em-up - Capcom Vs. SNK 2 - and the Dreamcast version of SFIII had online support to boot. In fact, the servers were shut down just recently, potentially leaving a void to be filled. On the other hand, Capcom's indecision about PS2 Online is understandable after sales of Biohazard Outbreak (Resident Evil Outbreak to you and I) proved lower than anticipated.
Although we tried to get in touch with Capcom Eurosoft just now, they haven't called back yet. Which is fair enough - we do badger them more than anybody else. Speaking from experience however, we reckon if it's in Famitsu this week, it's bloody unlikely anybody knows anything about North American or particularly European plans for the title. Still, we'll let you know if they do.
