Super Mario Brothers.Wii expected to sell 15 million units

Last week the latest installment in the Call of Duty video game franchise “Call of Duty: Modern Warfare 2″ racked up an amazing $310 million in sales and is expected by many analysts to be this year’s top selling video game.

While Modern Warfare 2 may be the biggest selling game of 2009, longer term the bigger seller may be Super Mario Bros.Wii which was released this week by Nintendo.
