We're still building ships and models for R1. In general if you haven't seen it yet, that's cause it's not done yet. So since you've only seen the Raptor cockpit that should give you a clue about other things we still need.
We're not intentionally keeping people in the dark here. Whenever we have something done we'll show it off. When we get close you'll know cause you'll hear us talk about the beta test, multiplayer testing and voice acting.
