I took it as "It should come in 2016, but considering Wave 8 delays I can't promise it will."
Wave 9 may not be out in 2016. Ouch.
Ouch, that's a rather longer gap between waves than I was expecting. Is that a worst case scenario, or the probable date? (I'm not currently able to listen to the podcast.)
Edit: Although I guess it would make sense if they're looking at a decent proportion of it being Rogue One related.
I'll say that was my interpretation as well.
