Metal gear has appeared on the Xbox 1 before, Kojima seems to want to express his artistic vision on the best technology. I think this is a distinct possibility. Also depends on the sales, this is a very expensive game to develop and the next one even more so. Relies on massive sales to payback massive costs.
FFXIV - Has never been on the Xbox before, but rising costs could force the developers hand into releasing this one multiplatform. Furthermore low sales in Japan means that they would want to seek the widest market possible in what is becoming a niche genre. The Xbox dominates the english speaking gaming market. The obvious choice for a port. Depends on the sales of FFXIII.
GTVI? - Im not sure, since sony doesn't own the company it's up to them. The lure of money could do it though.
Tease.
