Hind DLC!
(j/k)
I think if they get all the components right for one ship then I'd be far happier than if they had mulitple ships but with less features all round.
From that gameplay trailer, if it is to be believed, then it looks like they've got all the basic features of an Apache in place. The FLIR looks great and the 30mm cannon even sounds realistic. Kind of puts the recent gunship segement from big-budget MoH to utter shame.
I just hope the guncam/FLIR segements from the trailer aren't on-rails single-player missions. I want to be able to switch to co-pilot and guncam at any point during flight. The co-op aspect of the game looks all the more awesome at this point.
