Yeah, Trainworx was hit hard by the manufacturer shutdown in China, and then, just as the new factory was getting going good, this virus hit. Today's email from Pat says the factory is back up to speed, so hopefully we'll be seeing a lot of stuff soon.
I have a bunch of those K100 and W900s reserved. The last I heard he was hoping they'd be here in late Spring of this year. With this virus I expect that may slip to late Summer, but we should be seeing them soon.
