I imagine this'll be a case where it'll have my old name (Brett) but it won't have my new one (Charlize), so that'll be...I dunno.
I've long complained about how games like Mass Effect never have anyone refer to your character by their first name, so I do think this is pretty neat. But, I think the long term eventual solution to problems like this will be some sort of Miku-like voice synthesizer. Once the tech gets good enough that it doesn't sound like robots.
Also, let's hope the names aren't gendered (ie, only some names can be used by male characters, only some by female).
