Microsoft Entertainment and Device President Robbie Bach announced that 'Halo Reach,' a prequel to the wildly popular 'Halo 1,' will also be released this Fall. With over 300 million copies sold, Halo is a bona-fide digital entertainment phenomenon. Bach also said Xbox users can also expect the next installment of the massive 'Call of Duty' franchise which will be coming soon, and exclusively first on Xbox 360.
This would be quite huge! So MS has Fable, Halo and CoD for the fall.
Sony probably has Agent, Last Guardian, Resistance 3 and LBP 2?
Not sure though if that is enough...
