Short answer is no.
Nurgle release has seemed inevitable for a long time and new Beasts of Nurgle, based on the new art from 40k, seem to be coming along with the ever-rumoured GUO kit. I would guess that these will coincide with an aos book. There's no timeline.
Only other thing that's accepted to be in the pipeline is 'Cthulhu Elves.' We expected them to be out by now but it's all been quiet on that front.
Maybe they'll have something at BnG.
