The big question IMHO is, what do we make of the Amazing Sliding Nacelles?
I mean, the way the pylon structures cradle the nacelles is very suggestive, as are the pronounced rails atop the nacelles. And there seem to be nine round features atop the nacelle that might suggest nine positions to which these things can lock, as they slide forward or back.
I sort of like to think that the sliding is for real, and is intended to accommodate the rebalancing of the ship as something really massive is deployed from between those engine booms.
What is the closest real-world analogy to such a thing? It would be a barge carrier - a vessel that loads up on very large "auxiliaries" by virtue of doing some creative self-flooding, and utilizes rails and other sliding functionalities for handling those barges. A barge carrier might be a very nice ship to have when one assaults a defended planet: a massive, armored barge dropping on enemy positions could stand a greater chance of achieving something than a wave of tiny shuttlecraft or an easily disrupted transporterbeamful of troops and vehicles. OTOH, such a ship would seldom be seen outside planetary assault scenarios, and might not be part of the very first wave on those, either.

Interesting...one of the Excelsior study models had some kind of extendable neck-like business as well, didn't it? I wonder if the Norway-class ships can carry various sorts of modules and such back there. That would be...kinda awesome.
