I would have also very much preferred Elite 4 to be a single player game building on the mechanics of Frontier and First Encounters (though possibly with more interesting combat) however I don't see much point in dwelling on that since FD are not going to change their plans at this point, no matter what.
Well the good news is... you can still play completely SP with the only connection to Frontier server used as a continuous update of the galaxy.
Ain't future just amazingly bright?
