Could Microsoft have Final Fantasy XV marketing rights?

A recent poster sparked the Xbox community about a potential Microsoft and Final Fantasy 15 deal.
A poster was put up at the Microsoft Theater showing the characters of Final Fantasy 15 and a large Xbox One logo at the bottom. Although there were no specific details about the deal at the time, the poster is the same one that has been used for Battlefield 1 advertising which has been confirmed as being part of an exclusive Xbox One partnership.
The poster was later confirmed to just be a part of an advertising campaign used at the Microsoft Theater and there is no deal between Microsoft and Square Enix.
