I'm not too sure how they are going to continue it. SAO and Alfheim both had a common theme of Kirito going after Asuna, so it was natural for them to bind both arcs together into one season.

On the other hand, GGO does not really flow into any other arc. By itself GGO can be covered in no more than 10-12 episodes. Unless they are planning to make it a very short season 2, I doubt they have enough material here.
