My only concern is that having instanced ships where multiple people are walking around during combat and then having lets say 300 ships in that battle all with people walking around those instanced ships. I just shudder at the amount of calculations being applied to the server and latency issues. I don't care who you are or what your company has. I have been in MMO games in large battles and there will always be more people and assets on screen that the servers can handle...if you tell us we can have 500 people fighting at the same time and not get a single bit of lag or errors that is awesome....but we will bring 800 and crash the server. you upgraded the server? we can have 1200 now? awesome but now we are bringing 1500 and the lag is so bad i cant do anything....i lost my ship or assets ...my avatar got stuck in a moon when the game froze and i couldn't steer my ship.
The point is no mater what awesome way they come up with letting millions of people play together and have their awesome assets on screen together. the player base will find a way to tax the system to a breaking point...Would i like to walk around a large capital ship...sure...but i would rather have fluid game play and stable large fleet battles and warfare.
