If you’re set on picking up the HD release of Final Fantasy X and Final Fantasy X-2, you’ll have a couple of nifty options at launch date, since Gamestop is offering a free limited edition upgrade for pre-orders.
Sadly, there’s a dearth of information about the differences between the limited version and the normal ones. It could be minor stuff like a free soundtrack or an in-game item, or something big like an art book, or even a figurine. You just never know what Square Enix is capable of (besides NOT release an HD remake of Final Fantasy VII).
Final Fantasy X/X-2 HD is due out this year as a single release on PlayStation 3, and as separate releases on PS Vita.
