The characters in Xillia, aside from Mira, kinda bore me visually. Either way, I try and stay away from most of the spoilers in hope that if it does get localized, it'll be brand new experience. Even after all this time, I know all the characters in Graces, but that's about it.
Only reason I stopped with Innocence, is that it just didn't feel right trying to play with a keyboard. I hate playing games on the computer already, much less action games that require some button mashing.
