I saw a press release from Sony today about the North American release, and I must be having a stupid day. I think I understand that there's no cross buy, so if I want the option to play this on PS3 or Vita and take advantage of cross saves, I'll need to buy the PS3 collection with both games, and the Vita version that's just Final Fantasy X. Do I have that right? I don't really care about X-2, so that's not a huge loss.
I love cross buy, and cross save, and cross play, but sometimes it's a nightmare to figure out how to get what you want.
