Yeah, the wind suit thing looks interesting. It would seem to make the vertical game more interesting. Could end up being just a gimmick, but it looks cool. I also hope the flight controls are better. I could fly a helicopter fairly competently in BF2 and BF3, but I think they changed the controls in 4 and I never got used to it because I would get shot down before I got a chance to figure it out.
And neve mind the jets. I could fly them, but I never won a dog flight and always crashed when I tried to strafe. Part of it was that I never got all the stuff you need unlocked. Like the homing missiles and chaffe.
