Won't knock anyone's proclivities to literally throw their money away more than I already have... but hair DLC? That doesn't bother you guys and girls? I'm all in favor of a patch, but I'd rather they spend their time on new regions and campaigns. Maybe I'm wrong here I don't know.
I dunno, man. BioWare always releases appearance packs with armour, weapons, clothing, and accessories. They did it in ME and DA. So....my train of thought is this: the devs insisted the hairstyles were locked in. Would the suggestion of a patch even be considered after saying that? Maybe. Hell, hopefully. But DLC will most definitely happen over the next few years. You'll get your campaigns as usual, and there will most likely be - as usual - appearance packs. They can include hairstyles in the latter.
Would I prefer a free, expedited patch? Of course. But I'm weighing all options, trying to look at which ones are more likely to occur.
