There's little indication that Frontier are embarked on large scale development for ED and I really wouldn't count on it. If anything turns up I'll be delighted, as long as it doesn't require a further year of fixes.
IMO, there is NO indication that FDev are embarked on large scale development for ED.
Post budgetary cuts that happened last December/January, their patch schedule moved to once every 3 months with little dev happening (disregarding the story advancements) and with a vague promise of a major feature revamp for the next year.
Bugs get to persist even longer. Lots of recurring bugs. CM team engagement even lighter and so on
We even got features announced in the PatchNotes that never actually made it in the game.
To me this looks like the game is running on a very very tight budget
