Yes the 429 never looked much like the MAPL did it!
The Heli-Expo talking point concept airframe looks a bit like one of the MAPL drawings though. The fan in tail in the concept mock-up was also in one of the MAPL drawings and of course may simply be a NOTAR.
The problem with the illustration is that it has a rotor in shroud and we all know that every other manufactureris shying away from anything looking like a Fenestron. Bell have flown t/r in ring, AW flew a 109 with what was 80% a Fenestron but in the end they seem scared of having another 'skid gate' .... a day in court...
The moral of this story is that it may be simple to draw a concept airframe but the engineering has both copyright and other issues.
