Probably it does lose coherence. What specifically that means has to be shown in the future by working theory that accepts GR and QM as its limit cases...
Whether it will be any of the current research directions called quantum gravity or something else is hard to predict.
I have no intuitions here, as I am between a mathematician and a programmer and have catastrophically not enough knowledge of physics to try to predict unknown areas of it.
