I think it's because they know that the Vita is essentially dead in the water here in the states. It is a shame; I love the Vita and think this game would have been perfect for it. Still, I'm pretty stoked about this title. Folks keep saying it's a spiritual successor to Chrono Trigger, when actually it's a spiritual successor to a bunch of RPGs of yesteryear. I recall a developer saying that Chrono Trigger was one that inspired him the most.
