I'd love to see ME:A continued, but I dont think if another is made it will continue the Andromeda story. Even though the rpg and open world elements made this my favorite of the ME series, even with the weakest story, it unfortunately has a bad stigma to it due to the all the issues upon release and other technical issues.
My guess is they would try for something brand new, but their biggest challenge is if they go back to the Milky Way how to handle the results of the Reaper Invasion since players chose how it concluded.
I'm not an MMO player so I wouldn't want to see it in that form.
