It is clear that the total number of adult novels in the traditional sense that are released per year has dropped, but that was the case even in the LOTF/FOTJ era which always baffled me as they were the primary medium at the time. The reason this is cropping up is we have WAY less lead time on announcements now. Back when Sue Rostoni was on TOS forums/blog we'd find out hints about new novels up to a couple years in advance. We'd have general plot summaries up to a year before. Now, Disney keeps things under a much tighter wrap and we find out at best a few months in advance. So that can make it seem like even fewer things are in the works. My bigger issue is that the novels are now quite restricted in the type of story they can tell, because every major story will now be told on television or movies. It really takes away from the "multimedia" universe aspect when only one medium tells all the truly impactful stories. That said, Bloodline, Battlefront and Thrawn have all been excellent, so quality has been pretty good. (Aftermath series had a good premise as well but terrible writing) Given the relatively reduced output, I don't understand why they couldn't release a "Legends" universe novel once every 6 months. More revenue for them and keeps us traditionalists happy.
