The whole reason they aren't giving it too us is they don't want people to see it until their happy with it.
I dispute that. The reason, IIRC from the last live stream, was that potentially negative feedback from let's plays, twitch streams, &c. could turn into negative press and negative sales. I agree with that and that's why I don't support inclusion in a beta build until it's ready.
HOWEVER, a well-edited video of the combat viewer with large fleets (and maybe the winning starship design?) might generate some decent hype. And this I would support.
