As the title.... Is this it?
Not complaining or anything...just curious, the beta ends once you slay the skeleton King?
On a different note... (and can't speak for everyone, only for myself), Diablo3 might as well be the true WOW killer. The game is incredibly well made, the graphics are jaw dropping, and when I log back to WoW I feel like Im going back in time. Once you play Diablo, you can't really go back to WOW...and have fun.
My 2 cents.
