Who's to say the Citadel survives though?
I mean, the Citadel is essentially a superweapon/doorway to Dark Space and nobody has the keys to shut it. Who would want to keep that thing around?
There are other places for the Council to set up a hub...and I'm sure that say in the years post ME3, someone got the brilliant idea of "We can make our own, better Citadel! And it won't have that pesky doorway!".
Plus it would be a great teambuilding exercise.
I read a part of the above as "There are other places for the Council to set up a pub..."
Ladies wearing sombreros get a free drink on Margarita night. Come on down! Every hour is happy hour at the Citadel!
In all seriousness, my two cents:
- the wreckage does not necessarily have to be the Normandy. If you look at other ships the Alliance has in its fleet, and if you read the "Invasion" comic, you would see that the design used for the thrusters does appear on alliance vessels quite commonly. Saying that thing is the Normandy because it has those thruster is to me like saying that gaudy street-racing car is actually a Bugatti because they both have a rear spoiler.
- another galaxy is a neat idea, I guess, not sure how I feel about the Ark Theory, but it makes sense, I suppose. Seeing as we literally know nothing still, I shall reserve my judgment for when more information does surface.
- it is going to be super pretty, though.
- that Prothean - like (???) figure standing next to a human in the galaxy map picture kind of reminds me of one of the teaser shots released on last N7 day - it showed a concept of a Prothean-looking dude in a Japanese-esque armor next to a dev; even had those horns that samurai armors had. Dunno, its just that this is the first thing that made me think of.
