The ERJ family of aircraft would certainly be interesting for the sim. But each new aircraft model takes months to develop which is quite costly so it has to be an aircraft that is worth it. The ERJ family might be, but for us it's currently much easier to add new variants to existing aircraft such as the 737-800, -900ER and MAX or the 777F and 777-300ER. This way we can save a lot of time but still offer great new aircraft with new airline liveries that we did not have before.
This assumption is false, here is why:
The traffic aircraft model is much to low resolution and cannot simply be "refined". That model is made to be loaded at all times and be rendered up to hundreds of times each frame. It only has about 10,000 ish vertices, maybe a dozen of objects (wing, aileron, flaps, rudder, gears) and a single texture.
But our aircraft that you can fly have up to 500,000 vertices (that's 50x as much!), a fully detailed cockpit and hundreds of textures and high quality materials, not just one. And it has literally thousands of individual parts that all can move independently (small details, all cockpit switches, etc.).
So it does not make any difference what so ever if there already is a 3D model flying around as air traffic.
