MW5 is indeed real, but they are currently tied up with legal issues. (Concerning intellectual/art property rights? ? ? Harmony Gold just like last time.) The game is complete, the legal paperwork needs to be cleared.

. As best I understand things, the "Unseen" "Mechs became "Reseen" after the conclusion of the last lawsuit which Harmony Gold lost. As a result they were included in MW5, which confusingly, prompted yet another Harmony Gold lawsuit. What the final disposition of the MW5 game and the Unseen/Reseen 'Mechs come to remains to be. . .

A >>MechWarrior movie<<
has been optioned as well, but there has been no word on recent progress, if any. Briefly, some years back, there were persistent rumors of a Crimson Skies TV series, but to the best of my knowledge it never went past the conceptual (or outright rumor) stage. There was an official announcement by Dreamworks of a >>Crimson Skies Movie<<
. But, like the MechWarrior movie, there has been no other news reported since that announcement.
