I emailed them the other day, but as it turned out I hadn't been reading or receiving the Rapido UK newsletters - archives here https://rapidotrains.co.uk/rapido-news-uk/
As per the newsletters, they're shipping out from the factory soon. They'd been waiting on ESU decoders by the looks of it.
Here's a portion from the email I got back
"However, just so you know, the APTs should leave the factory in the next few days. They’ll probably land in the UK mid-February but it’s here that it gets tricky because we’re then completely in the hands of the shipping companies and we won’t know when they’ll arrive until about 24 hours before they do."
I'd certainly take everything regarding supply chain predictions and delivery with a tub of salt. I work for a manufacturing company, and can honestly say it's a nightmare out there. Unplanned decommits, random delays, random shutdowns, random deprioritizations, lost consignments, split (and part lost) consignments... the list goes on.
