Next Mass Effect Game

A few years ago there was a teaser video about the next Mass Effect game. Seeing as how the next game probably won't come out until 2028 and the developers could change the entire context of the game, what are some things you'd like to see happen in the next game.

For me, I'm a big trilogy fan (never cared for Andromeda) so something I'd like to see is the Quarians without their suits. I'd like to see what Tali looks like. Also, this is going to sound far fetched probably, but what if the antagonist was Henry Lawson, Miranda's father. Sure she "killed" him in ME 3, but we never saw a body. What if he escaped? Stranger things have happened in video games.
