No one can doubt the power of the Grand Theft Auto franchise, but just how strong is the brand? Analyst Michael Patcher estimates that the downloadable expansion The Lost and Damned will break the 2 million download mark this year.

"Take-Two released the first installment of DLC for GTA in mid-February, and we estimate that the game has been downloaded over 1 million times to date," said Patcher. "By year-end, we think that this figure will likely double, giving us greater confidence that Take-Two can achieve its full-year earnings guidance."

The expansion costs $20 and is exclusive to Xbox 360. It can be bought both offline and online, though it still has to be downloaded through Xbox Live.

Patcher additionally expects the next full release of GTA to outsell GTA 4 by up to 50 percent due to larger hardware install base.
