The boss of SideQuest Studios, the Italian team behind the newly announced PSN game Rainbow Moon is thinking about doing a Vita version. Marcus Pukropski's translated comment is, "We are currently considering developing a version for PS Vita, so it is certainly a possibility. If we decide to do this, however, it will take a long time. So if you are an avid fan of Rainbow Moon, unfortunately, over the next months there will be no alternative to the PSN version."
The turn-based combat and exploration game would look pretty good on the Vita and should be a fairly straightforward port. Hope this does happen.
