Thanks!
I don't expect they will.I'd say the odds are very big that yes. If I'm not mistaken that's what they did with the Wii U version of ME3.
I still hope they might rework the endings beyond that though.
I preferred the extended cut ending above the ending it launched with, but it did screw with the pacing and tension in one of the last playable scenes in ME3's OG finale IMO.
