How about we get the other fenrir mount as well? Or maybe a Tifa level for the brest slider.

A different question: What about things that XIV could give the VII remake? You know like the XIV remix for the Gold Saucer. Maybe Primal music for the summons. *cough* Knights of the Round *cough*

The Final Fantasy series went a long way since the original so all the new games are bound to affect the remake. Maybe the Shantotto event will return in VII instead.
It will definitely have DLC so costumes and weapons are also likely to show up.

Hmm come to think of it, off topic or no I would kill to see Tifa in Class Zero uniform
