While this thread asks what
we would like to see happen to Type-0, the actual reality is that Tabata said (in the
USgamer article in the OP) he would like to distribute it in the West soon via PlayStation Network. I know this doesn't explicitly confirm he meant a PSP release, but it does
imply it due to the sole fact they want to distribute it digital only. If say, they were planning a Vita port, then Square Enix would be distributing it physically as well, not just digitally.
So with that said, I can guarantee you they don't plan to port Type-0. It will be localised only for PSP via PlayStation Network. Also remember that even if it were getting ported to another platform, this would mean a new release for Japan too. And since nothing has been announced for Japan at this time, the chances are pretty certain that the West is only getting it for PSP.
