I just watched a video with alot of speculation on this, its one possibility to continue the story. Never thought of that can see how it would link into mass effect 3 for carryover saves.
Whilst there’s some confirmations there, only speculation at this time about Shepard having a possible child as the lead character. If it turns out to be true, that’s awesome.
A newer video has confirmed the Mako will be returning, further its been predicted it may release sometime April or May next year.
