Rainbow Moon was a quirky throwback to the classic Japanese-style strategy RPG, complete with quick tactical battles and an extremely lengthy story mode. In other words, it's exactly the kind of game you'd want on a portable system, and publisher EastAsiaSoft has announced it's making that happen.

IGN reports that the Vita version will hit sometime in 2013. The studio is aiming to include cross-saving between the PS3 and Vita versions.

Now for the bad news: it won't feature the cross-buy promotion that Sony is implementing with many of its first-party products. That means if you already bought the PS3 version, you won't get the Vita version for free. EAS' Nils Ngai noted that the studio can't afford to bundle the games for one price, since it wasn't built on a framework for both platforms and needs to invest an estimated nine months to port the game. "We are definitively looking into discounted options for customers that wish to purchase both release versions at the same time," Ngai noted. "We won't be charging double the price if you want to buy both releases at the same time."

Meanwhile, Rainbow Moon developer SideQuest Studios is at work on another game for 2013-2014. EastAsiaSoft still plans to work closely with SideQuest, though it may look into other platforms as we enter the next generation. Aside from the mystery project currently in its conceptual phase, Ngai noted that a sequel to Rainbow Moon or porting its Soldner X games to the Vita are possible future projects.
