We all want the impossible, for a remake of a game to top the original, to be a definitive version of the game. I'm sure Square feels they have better things to do in the long run, but they might change their mind. There's not really a lot we can do about it. If anything, they're going to be paying attention to the Japanese market first, seeing as they are based in Japan. It's been a running trend in the game industry since Japan took the lead in the 80's.

Final Fantasy VI is the most "Western" JRPG that has ever been produced. They managed to work in a WW2 theme, jokes about political correctness (I'm a TREASURE HUNTER!!), and to date, the darkest thematic content that a game in the series has since broached (After the End, anyone?). They clearly hoped it'd sell well in America. Sorting out the stew of what they want to put into a remake will take time.
