Actually, 30$ for the game and all DLC is pretty correct as a price, considering the game is only 3 yars old, and it had been lowered to 15$ for the update so I'm sure lots of people took advantage of it. And yes, those who previously had the retail version can register it on Steam and get the full game and DLC. Also, registering it on Steam won't require to use the disk anymore, which is a relief.
