I don’t think it can be addressed that quickly
you must know that the SU7 is already in testing 
Also, if we need for example a low poly version of each existing planes from devs/ studios/ modders so we get where we have a library of multiplayer planes representations to choose from, it’ll certainly take even more time !
But as I tend to joke about during alpha, “hey, MSFS is a platform that will be ready in 10 years, not a 10 years old platform !”
