I don't really have any expectations. Because now the story of Shepard is and his crew is over it feels as though Mass Effect is done and dusted. The ending was final and citadel dlc was the final goodbye.
A new mass effect game would feel very weird, and frankly I think that they have written themselves into a state where there only hope to continue the story is some type of reboot of alternate timeline...which I would not really like.
I'd say safe bets would be: Combat similiar to Mass Effect 3 but a bit more improved, really good graphics and visuals and probably some decent characters and story. And of course lots of overpriced DLC, microtransactions and multiplayer.
