I hope that with MS Flight comes a built in ability to fly online using peer-to-peer on VATSIM or alike. Without the need for a addon to the game. It could mean that the game has less chance of crashes and so on. Especially so since those online networks are the things keeping the game alive. This would also be great with a store system that allowed you to purchase aircraft to stop pirating. I can't wait for this. The potential is huge.
