It is very difficult to tell whether the xbox one version will perform, Amazon software aren't very reliable. That said, the xbox one version will depend heavily on American to sell the game this time compare to FF13. Final 13 sold on 360 200k in ROW last gen which I don't see nowhere near that this gen. There should be also a huge decline in Europe considering ps4 has eaten a lot of marketshare from 360 last gen. And xbox has not been dominating US either so it's unclear whether the xbox one has enough JRPG fans for the game. Last gen made more sense due to the fanbase being split between ps3 and 360, not so sure anymore. Anyhow, square need to release the game on xbox one to know if there are enough JRPG fans in the system to keep releasing future FF games. This is a mainline game, it should sell enough, if it don't, it will be very hard to justify spin off release for the console.
