Rock Band 2 moves 2 million units, but sales are lower than expected

Viacom said this morning during its Q4 earnings call that Rock Band 2 sold close to two million units across all platforms since its September release.

As nice as these numbers sound, they were lower than Viacom was expecting.

"While we remain enthusiastic about the future franchise potential for Rock Band, the impact of a slowing economy dampened consumer purchases of videogames in the quarter, resulting in lower sales of Rock Band than we had originally hoped," said CFO Tom Dooley.

International sales for the game were $462 million, and the Rock Band franchise as a whole has shipped over 10 million units since its November 2007 release.

Edge reports that Viacom showed an overall 69 percent drop in net earnings to $173 million for Q4, with $454 million being spent on restructuring charges.

Quarterly revenues were $4.2 billion.
