Actually I don't care to have it as a flyable. I would prefer a CH-47D or E myself. But they have a soft spot in my heart. ;)
As for it dominating the battlefield.... it would be able to hold it's own, but from talking to the test pilots, most of them actually preferred the older Cobra models. A LOT of the technology in the Z is just unreliable right now. Of course this will be improved and systems will become more reliable over time, it's a process. The dual role cockpit is handy, and it can be very nice if one of the pilots is incompacitated during flight. The new controller looks like it was directly taken from the Playstation too. It was rumored during engineering stages that they acually used a PS controller to get the right "feel" for it. lol
