First of all, I said it a lot of times before, is not the same sharing a cockpit, than two separate cockpits. And talking about promises, ED promised multicrew for the Huey and is still not here, I wonder why... About PBR, I am sure they will end up doing it. Meanwhile, they solved the shadows problem.
EDIT: And It happens exact the same for the MI-8 which doesn't have neither multicrew and PBR
