Cleaver strategy. Release a decade old game on a different platform that is for a niche audience that your audience should already have in spades. If the game sells well then you know you have an untapped audience of the platform, and if not then you know you don't have to develop for it. That's what they used Phantom Brave for with the Wii, and Disgaea on the DS, and Atelier Annie on the DS as well. I suspect this will be another proof of failure for the PC, and they'll get next to nothing in the future like the Wii, and DS.
Unfortunately if you're interested in these kinds of games like I am them you area already aware that if you want reliable releases to get to you then you need to have a Playstation. This knowledge ensures the vast majority of their market is already being sated, and these test runs are all ,but ensured to fail. But maybe if the stars are aligned then maybe.
