probably PC, I think XB1 is still in the air; the sales disparity between Type-0 was pretty large in favor of the PS4, plus the install base isn't what it is last gen. MS had a sizable JRPG install base because at their push of JRPG's like Lost Odyssey, Blue Dragon, Infinite Undiscovery, Tales of Vesperia, ect. that's not the case this gen, PS4 has basically already cemented itself as the JRPG this gen and that's not going to change.
I think the only possible way this comes to XB1 is dependent on how well FF XV and KH3 do on XB1 and the overall install base; and I already have my doubts with Kh3 as the Xbox platform has never had the KH game on the console(unless S-E does a collection set for PS4/XB1) and with FF XIII despite the 360 having a greater install base the PS3 still outsold the 360 version handily now with the PS4 having the greater install base might diminish the sales of the XB1 version as well
