I'm very interested to see the new options that mega-ships will open up. I imagine they might be a precursor to the ability for commanders to construct permanent fixtures/structures of their own in space, or in the shorter or immediate term to act as carriers for hyperspace jumps. It would make wars more interesting and coordinated if larger squadrons could arrive at the destination together and launch in unison for attack, with the idea being that a mega-ship can support a very large and super powerful FSD.
Dolphin looks nice, and the Holo-Me is above and beyond what I expected. Flying around with the external ship-locked camera with rotation unlocked, through trenches and between asteroids will be great fun. All in all some HQ updates, which makes me more hopeful about what multi-crew will be like in demo as opposed to on paper.
