BW NEVER annonced "major" space combats.
They clearely stated space combat would be only a minor distraction. Idk where you think you are tsaking your facts, but I red everything from BW since the day the game was annonced and that includes everything they said about space combat.
What we have now, is what they told us we would have and in totally fine with that. BW gave us space combat because poeple asked for it and thats already something very nice of the.
They already stated that the new space mission is not part of the "Future of space" project, but guild ship are part of that though.
