Activision Blizzard has said that, Call of Duty: Black Ops, which is set to be launched on Tuesday, is expected to become the largest selling videogame of this year.

The game is expected to sell between 13 and 15 million units in the quarter and is expected to generate high revenues from digital sales as well. The earlier version of the game developed by Treyarch, Call of Duty: Modern Warfare recorded high digital sales of its add-on products.

Research firm NPD, said that the digital sales could help the industry which has seen a decline of 8 per cent in the disc based sales in the year. Publishers loose on retail sales as users tend to return used games at stores and purchase other used games.

However, users are not allowed to trade digital add-on products like battle field expansions and game publishers are now planning subscription models for online games and are also planning to sell virtual goods. Meanwhile, Activision has reported a growth of 15 per cent in digital sales in the first nine months over 2009.

In another development, auto major Chrysler Group is selling a limited edition 2011 Jeep Wrangler Call of Duty: Black Ops model for the real world drivers. The company plans to produce between 2,500 and 3,000 units of the limited edition jeep which feature Black Ops graphics on the roof and front quarter panels along with high-gloss mineral gray wheels.

The starting price for the jeep will be $30,625 for two door version and $33,500 for the four door version. "This is the first time we have produced a vehicle based on a videogame and it may be a first for the industry," said Jeep Chief Executive Mike Manley.
