Wow, those are like looking at taken-at-risk-of-death pictures of Soviet military hardware back in the day.

Yup, you'd think it was a new, stealthy Mig or something...

These look like old "Big Foot" pictures.

Looks like it would compete with the Piper Meridian or TBM 850.

Nice to have some competition.

I hope there is more than 500 hp in there.

Definitely Mustang-ish, but...
1) a rear clam shell
2) seems like the section between the first cabin window and the pilot window (where the fwd door was) is gone
3) the light colored areas fwd of the wing and aft of the cabin door seem to correspond to where there are fairings on the 510

Here's some more info from AOPA Summit. If they can hit there targets and come in closer to 1M than 2M I may get in line!
