There were rumors, at least words from Jurgens, in the beginning that it was supposed to be a defintitive DCU future. But it never panned out or went anywhere. In the end New 52/Rebirth Batman Beyond is in the same boat as the original series set in the comics DCAU, in that it is in its own reality, world, tangent, or whatever. It'll just occasionally take concepts from a current main continuity (like it did with Jon Kent).
