There wasn't a ton of fanfare at the original launch. Through enough advertisement along with it launching on a console instead of the PC, I'm sure they can mostly overcome any stigma that was built up. Perhaps they could go so far as to add on a subtitle or whatever to emphasis that it isn't the game it once was.

Really the main thing I'd worry about is how they're going to convince the current XIV community to move to a p2p plan. I'm sure several will have a bit of a hissy about that regardless of how the game changes.
