From all accounts, the test numbers are within a poofteenth of the real world figures recorded by the low wing version, the TSi, of which there are quite a few flying already. I see they have developed a taildragger in tandem with the tricycle, rather tasty looking, even if it makes no pretence of being a STOL bird.
I'd guess that both in their home market and in the US, the ability to develop full power well into the teens is a bigger selling point than here. For most people, a big advantage over the RV, would be the relative ease of getting a factory built version delivered to your hangar.
