User blog comment:Historygeek1/Could the Andromeda Initiative have planned a way to return to the Milky Way Galaxy?/@comment-11209678-20170220180028

I do think that they will try to link the two galaxies. After the initial trilogy, you face a few problems as far as storytelling goes. Obviously continuity is a big one, with the different endings, but possibly a larger problem is who is going to be the next villain? It's hard to imagine something larger than the Reapers. If I were Bioware, I would have the introduction of Andromeda species to the Milky Way drive a stake through the Citadel Council, causing major division between the major races for the first time in millennia. If you think about it, without the Reapers, the Milky Way really isn't very exciting. Any of the forces that are hostile to the Citadel aren't strong enough to challenge it, ranging from the Krogan to the Batarians. Maybe the Terminus Systems could mount some level of an attack, but I don't think that's a story that would be very interesting. Introduction of Andromeda species could cause new alliances to form and upset the balance of power that has been in place for thousands of years. As you noted, this also gives them a good excuse for a huge time jump forward. After 700 years, you could rationalize that the differences the different endings made are largely gone, thus eliminating some of the continuity concerns. Will some people not be satisfied? Probably, but you can't please everyone.
