After only being released a couple weeks it has become clear ‘The Beatles: Rock Band‘ is a hit.

Sales of the video game and bundle have surpassed expectations, even those of game creators’ Viacom CEO Philippe Dauman.

Speaking to Wall Street analysts on Wednesday (September 16) at the Goldman Sachs Communacopia XVIII Conference, Dauman said the “Limited Edition Premium Bundle,” which sells for about $250 has been selling fast.

Dauman said the game is selling so fast that it may sell out by November and may not be available for the coming holiday season.

“If any of you out here want to buy some, you better hurry up,” he told analyst.

Dauman also revealed that in it’s first week release Viacom sold 25% of its inventory.
