Your return to the role of a Tier 1 Operator will be in a game called Medal of Honor: Warfighter, which will reportedly be out this October.
Game Informer's website, citing the latest issue of Official Xbox Magazine, is reporting that the heavily hinted-at sequel will once again be made by EA's Danger Close studio. They'll also be handling the multiplayer portions of Warfighter, unlike the last Medal of Honor game where the online component was handled by DICE.
Warfighter will use the DICE-developed Frostbite 2.0 engine, which has been used for last year's Battlefield 3 and Need for Speed The Run. More details can be found in the print edition of Official Xbox Magazine.
