I wouldn't mind a Red XIII or Mechanical Moogle mount. However while some character designs for the most were made for simpler more anime esque character designs. I can't stand to see Clouds hair style if its done to look more realistic. (I didn't care for the film version either).

Considering it did make all other FF titles more mainstream. I would not believe for a second that SE would not have some kind cross title promotion for or prior to its release. The question is will FFXIV have a dungeon involving the phantom train (like doom train in 6) ending with a reference the beginning of 7, mounts, or glam gear like the lightning returns event. Personally aside from a mount, I'd like to see some Shinra co. suits the Turks wear as glam gear. Heck were getting Machinist with Heavensward might as well look like a professional while shooting things. Then again we do have a Gold Saucer. Maybe it will be involved with an event instead of a world thing as with Lightning Returns..
