Coming from the company that ported the mobile version of FFIV to PC when ds version was better and an option, I just can't take them seriously. FFIV, the DS quality game, is looked to 15fps on PC. It's sad how lazy of a port that is.
They have a perfectly fine PSP version that you can enhance for the Vita. "We doubt it will sell much on Vita" would have been a reasonable answer.
