You make an interesting point. According to VGChartz:
FFXIII: 5.26mil PS3, 2.11mil 360
XII-2: 2.65mil PS3, 0.73mil 360
Lightning Returns: 1.00mil PS3, 0.22mil 360
Type-0 HD Pre-Orders in USA (as of week ending Feb 28th) put XB1 at about 2/7 of PS4 version's numbers.
Well we all knew FF sold better on Sony consoles anyway, so those numbers really aren't news. Some might argue that out of the many 360 owners that switched to Sony this gen (many which previously owned the PS2 but skipped out on the PS3), many possible XBOX FF buyers were lost; but of course we have no way of knowing that. Sony does get a lot of exclusives of Square as well.
My theory? It should continue the trend and sell between 2/7 and 1/5 of what the PS4 version does worldwide. However, I'm not sure if Square is ready to ignore a whole other user base for their main titles though; no matter if the sales are 1/5 of the PS4's. I'm no expert but I don't think the cost of developing for XONE as well outweighs the profit they might make by bringing it to the console. As for anything that isn't a mainline FF title (and is from Japan), I agree that PS4 has a good chance of locking them up.
