After all - Shepard can ask survivors for building synthetic body (like EDI) and upload their "I" to that body before shutting down last piece of controled hardware and survive as mortal synthetic.
This must be possible becouse, boy says reapers listen "You", then there must be way how transfer shepards "I" to another platform
And now we, all together can build our new own Citadel where new council will have residence and now there be presented all alied species including synthetic (very important)
One observation from me:
End of Mass effect series is exactly the same as end of Battlestar Galactica (new) in another suit and two more scenarios what Adama can order after beating resurrection ship
hm, is it intention?
p.s.: if that orders are not possible for some stupid reasons, like only one order can be send or something then sorry, but let them go back to dark space is the most stupid order what can send, shut down is much more better.
But we put the warning anyway, just in case...)
In Mass Effect 2, Shepard had to make a critical decision between the following options:
Destroying the Collector's Base
Leaving the Collector's Base to Cerberus
If you did NOT play Mass Effect 2, or if you started a new game on Mass Effect 3 WITHOUT importing a character, the assumed choice is:
Shepard Destroyed the Collectors Base
You can achieve the perfect ending whether or not you destroyed the Collector's base.

I doubt Bioware would create a game where the end is all in the protagonist's head and the one thing ever true Mass Effect fan wants to do, which is finally kick Reaper ass, never actually happened, and if that's how Bioware intended it then they did a really bad job because they left so many holes in their presentation of that theories ending. In conclusion to my big ass rant I feel the ending wasn't all that and a bag of potato chips, and I hope this DLC of extra epilogue scenes in the summer clears it up for all of us, but the ending of what I still feel to be the best game franchise I've ever played didn't necessarily live up to expectations but was fitting enough to keep me satisfied.
