Anyone who loaded up WoW this morning and patched their game up to 3.0.8 was greeted with a pleasant surprise--a slick new Blizzard Launcher. It looks to have been redone slightly, with a cold-steel Wrath-y theme and a more organized interface. Immediate additions I can see from my end are helpful community/forum links at the bottom, a well-lit link to the Blizzard Store right up top, and (of course) our boy the Lich King, stage right.
Tipsters have noted that it looks similar to Battle.net launchers, and this may very well be an intended change given Blizzard's past statements that Battle.net is up for a major overhaul for Diablo 3 and Starcraft 2.
Leave it to Blizzard to package such an anticipated patch in such nice foil wrapping.
