A check of RailPro Assistant this evening bought up something new. A listing for the HC-3 product program. Nothing about the HC-3 on the website yet but there is a explanation of the chip shortage on the "What's New" page.
Interesting to see whether the HC-3 is the same form factor and function as the HC-2 (ie, something like just a processor upgrade gets it a new model number) or if it's completely different.
