I'm not sure about Final Fantasy: Type 0.
That one I don't exactly blame them. Depending on their thought.
You can only release it once for the big initial sales (Which mean more profit). The PSP isn't really going to have great sales, so they might have thought about making it for vita. Except for those sales have been crap. So now it's ZOMG what do I do, release it on ipad/3ds idk.
What other games has SE not brought over? I think they just don't know what quite to do with/how to release it. They could just release it. As you say they could just port it to PSP, with a lot of localization, but idk.
