There will be precious few IFR piston owners with the dosh to buy anything at/over $1M. Perhaps 1% can. And I think those who have $1M can also afford $2M or $3M...
The EA500 comes near to $2M once you have all the goodies you want. Although I would wish that new aircraft find more acceptance in the markets, it is very hard for new competitors to make up for the experience of the established players.
Take your $2M and get a used TBM 850 and you will have more ceiling, range, speed and prestige and after a few years you will still get more money back for it than for the EA500.
Cobbler, stick to thy last.
