I actually did some comparison to OBR and IDK:
OBR: total warscrolls = 17 (of which 4 old so 13 new). New kits = 11.
IDK: total ws = 14 with 11 kits
Hence my prediction would be that we will see some sort of smaller monster or warmachine associated with "Scinari". We will see that the Stoneguard is a dual kit for a Scinari elite unit (with different helms and weapons, I think the cow-helms where made like that to easily distinguish them from the other version on the table top). We will then also see another generic hero that is a dual kit with a named char, i.e. similar to Liege-Kavalos/Zandtos or Akhelian King/ Volturnus for some more choice to use as a General.
I think we wont hear anything really until they have confirmed a date when their factories and shipping are up and running again because they need to keep som dry gunpowder and they simply don't have that much left and in particular since no one knows how long this lock down will continue (could easily be another 6-8 weeks), so they cant afford to continue the drip feed. When they have the date, they will announce pre-release and they will have quite a chunky update to bring up the hype again by revealing the "Scinari" aspect, that will turn out to be either wind or river, quite likely these units will also be a bit less controversial than the hammer/cow aesthetics so they can "end o a safe note".
This would bring us up to 14 warscrolls on 11 kits (i.e. same as OBR/IDK). They will keep Tyrion and the other 2 aspects in their back pocket for the future. But all in all that should make for a pretty decent amount of choice and cool units to build lists from, in particular if they make all of the three basic units decent enough to be viable choices so we avoid the IDK situation of only eels (i.e. their elite) being really playable.
Just some thoughts but I wouldn't go down the despair well just yet and as others have said, sure with hindsight this didnt play out that well but no one anticipated how far the effects of corona virus would go, in particular not in Jan when they planned all this. And yes someone made the decision along the way to thin out the content by going with a lowdown every 2nd week and they probably thought that would carry through the crisis but they underestimated how long it would take... so now they kinda ran out of ammunition and hence the lid on until they can open fully again. Thats my thoughts anyways.
