But he never mentioned the helmets...
Press Release says:
"Also included in the Halo 4 War Games Map Pass are two unique in-game helmets (Scanner and Strider) that feature new geometry, and an exclusive in-game emblem (Falcon). The Halo 4 War Games Map Pass is included as part of the Xbox 360 Limited Edition Halo 4 Console Bundle."
Then Ellis corrected and said LE of the game. It console. That implies helmets and all IMO. Guess we need more clarification.
