Jump Square has a list of projects tied to the Rurouni Kenshin Cinema Version. A new OVA is coming in June right before the live action Rurouni Kenshin movie on August 25.
Jump Square also reports a Rurouni Kenshin app is coming in May and a new game for PSP is in the works.
So, why the question mark? The link to the game’s site takes us to last year’s Rurouni Kenshin game, which also happens to be for PSP. I don’t think Jump Square, a publication from Shueisha, would say a new game is coming to PSP among a list of eight other Kenshin items slated for 2012 and mean last year’s release. Maybe we’re going to get Super Rurouni Kenshin Turbo this year?
