Three possible endings that really aren't that different from one another make it a lot easier to make Mass Effect 4 or whatever else that want to do to milk the universe for cash. Horrible way to end a space opera, but good way to insure you don't make the next game that complicated for your development team/writers.
Lazy and greedy.
Bioware said any new Mass Effect games would be set either prior or during the Shepard Era. There are no plans for post-Shepard games. (or at least, there weren't. Now that they've fixed their universe, maybe they've changed their minds.)
