Do you know of any MMO's in which the developer has actually stepped in and name-locked as you call it? I've heard of them removing names due to copyright problems (CoH comes to mind), but I've never heard of them removing names because of any of the reasons you're listing. It's doubtful Bioware will step in. I know you see this as an unfair advantage, but early access was meant to be just that. Bioware said up-front the earliest pre-orders would get into the game first, and that would obviously mean name rights as well.
