"In the years prior to 2007, the Call Of Duty franchise excelled in delivering the consumer with a realistic, gritty taste of the life of a soldier in the Second World War; however, it became abundantly obvious that with each release, the series began to lose it's appeal. An injection of life was needed, a re-imagining of the series was compulsory if it were to succeed. Come 2007, the world was taken by storm. The decaying series received the much needed change it had pleaded for since Call Of Duty: 3."
Given the way Tomb Raider been selling, SE would be crazy not let Crystal Dynamics develop another installment.
Seriously.
