At the moment we have the beta launcher/beta version of the game (I think). With head-start coming in about 2 weeks will we need to download another "live" launcher which will redownload the game? Or is the launcher and game files that we're currently using used for the live version of the game too?
(Just thought about this because thinking back on WoW you don't use the PTR client to log in, you use the "live" client.)
