I'm coming to a few conclusions about ED:
1) Offline cancel may help produce a more dynamic galaxy, but it REALLY helps DRM enforcement. Super win for FD there - probably a sensible business reason. If it was offline, I imagine the piracy level (of the game, not NPC's

) would be extraordinary.
2) The galaxy is so huge that a playerbase of hundreds of thousands can get lost in it. Online play might mean we don't meet each other all that often
3) I like online interaction in games. I don't play COD against bots - where's the fun in that? I'd like storylines based around some core systems to keep a lot of us there, minimise NPC and maximise chances of being with humans online. If you want to forgo that and explore, fine, but we need a hook in some core systems. However, the entire principle of Elite is and always was one person, alone, in your ship. ED is no different, and that is a little bland for online interaction.
4) The game won't become super popular - it's a niche game. A bigger niche than others, but still. The player numbers, limited social stuff and 32 players per instanced system will limit the feel of MMO (which it is but really isn't) for many.
5) I don't much care for any of the above - I'll play regardless and see where it takes me. If in a year the game is awful with nothing on the horizon, I'll just ditch it. Maybe star citizen will be out by then, or EVE Valkyrie and a consumer oculus rift, and ED will have articles like 'what Elite could have been........' on the internet. I hope they don't blame it on the limited finances though.
