Yeah, nooot really. FFXII always looked good enough to me, and I doubt my PS2 is going to crap the bed any time soon *knock on wood*
I was mostly looking forward to the extra content in X/X-2. If that will be there as DLC, then I'll still get the games. The game is a really good deal regardless, and though I'm not a fan of locking stuff as DLC, I don't mind giving in this time around.
And yes, I know that XII had some extra content in the international version as well. From what I hear, the extra license board content didn't save that from being a dreadful character development system.
