It sounds like an impressive little jet, very clean with a unique look. From what the crew was saying it'll do roughly 420kts true in the low 30's with a max alt. of FL430, on 250-300pph, per side. 7 people (1 pilot + 6 pax or 2 pilots + 5 pax), about 1180 NBAA IFR range with reserves. Not bad for what you'd be paying ($3.9m said the sales guy).
The interior was still in the test configuration, so it only had one fairly spartan seat and a bunch of computers and wires...so I'll reserve my judgement on that part, although they did have a hand out showing what it should look like, it looks nicer than any VLJ interior that I've seen so far. I guess the flight deck will have the G1000 but the test airplane had smaller screens than the production version will have, otherwise that was the same. Very cool to see an airplane with s/n P0001 on it!
