So
Jessica Merizan an employee of Bioware's has released some rather substantive hints in Twitter responses to things the ME3 Director's Cut is likely going to handle.
ADDITIONAL SPOILER ALERT DO NOT HIGHLIGHT THE TEXT
Substantive Details:
* Indoctrination Theory officially appears off the table.
* Mass Relays may remain partially intact and may be potentially restored after some time.
* Nobody starves on the new planet the Normandy crashes on, somehow.
* Shepard, if alive, may be able to reunite with his crew.
EDIT: Nevermind, brand new tweet now says "I'm not making any promises."
Still why would a Bioware employee come out with those kinds of statements if they weren't true? Seems a dick move if she was making it up.
