Honestly, an awesome showing of FFXIII would be infinitely more interesting to me than an FF7 remake.
I bought Unlimited Saga and enjoyed it for a bit, but honestly the battle system was too obtuse and random for me to enjoy. The reels were fine but a pain in the ass to use, and I ended up getting tired of it.
The field stuff was actually really interesting, and it really made you think about how to grow your characters, but the game was ultimately unsatisfying because it was so obtuse.
FF7 was infinitely more enjoyable, although the battles were definitely a pushover. If they remix FF7, I hope they give us a "hardcore" mode or something, that makes the status spells useful and ups the difficulty.
But again, bring on FFXIII before FFVII.
