I checked Wikipedia and the SAO novels currently have 14 volumes in addition to a few spin offs and are still ongoing. The anime covered volumes 1-4 and the second season is going to cover 5-6 so it will get to 50 episodes without covering half the source material. Assassination Classroom is a possibility if the sales increase.
