Alright, guys, there is only ONE Su-47 in existence. The PAK FA is set to enter service in 2015, a year after the game takes place, but so is the F-35. The F-22 Raptor would be unnecessary, and if the PAK FA were to be added, it could simply be countered by an F-35C, which wouldn't have to have it's maneuverability nerfed to compensate for VTOL, and would be cheaper/easier to add than an entirely new model like the F-22.
