As FFXIV is a multi-platform mmorpg from PS3 to Windows... an advanced character customization is unlikely to happen, unless the lesser hardware is removed from the cycle.

Most MMORPG's these days have amazing character customization features, but most MMORPG's are PC exclusives. Looking at Blade and Soul for example, a high quality MMO from S.Korea many years ago (now in closed beta NA), has an amazing character customization feature. Almost like similar to how SIMS characters are made. But as I said, this one is a PC exclusive. Doesn't matter how much data is created.
But with FFXIV, we have PS3/PS4/Windows/Mac... limitations are at every corner and data has to be cut to get around. Not hating on the PS3 (I own all Sony crap, even the Vita), but it simply is holding the entire game back.
If this was a PC exclusive...
