Think it will look fantastic, sound fantastic, and be the best dogfight game yet.
Think the ground war will be sterile and very limited particularly in object numbers on map, and co-ops non existent, and the worlds worst FMB bundled in, and require a monstrous connection to host.
If you only like dogfight servers, it will be the best game ever, if you want more from a flight sim, its going to be another slightly missed opportunity imo.
