That's a very interesting aircraft, but I'm not sure that it will be a civil aviation game changer. The designers are obviously still fine tuning the design, because in a couple of photos, winglets are in evidence, whereas in another they are not. It's tough to get a feel for the wing planform, but it appears to be a very high aspect wing with a very critical air foil section. My guess is that it would be relatively unforgiving in poorly-managed slow flight regimes. The very high aspect ratio vertical stabilizer and short ventral fin seem to be a bit of overkill in yaw dampening, but I guess that something would require a ventral structure to prevent prop damage in over-rotation scenarios. Anyway, it's a pretty cool design, and as Pattern Is Full stated, is somewhat reminiscent of the Piaggio.
Just my opinion based on a stance of relative ignorance of the design.
