The ViperMS is an auto-switching (left over right priority) YPbPr switch that is fully modular. You decide how many inputs and ouputs you want to have on your switch.
While technically you can add an infinite amount of modules, the amount is limited to how much power your Quickcharge or Power Delivery USB-C powersupply can deliver on its 9V rail.

Switchable signals:

YPbPr (all common resolutions up to 1080p 60Hz)
S-Video (all common resolutions, signal needs to be split to 2 RCA connectors )
Composite (all common resolutions)

Currently we are still in development. We already have working hardware and are now working on the software side.
As for when the ViperMS will be available, we cannot say yet, but follow us on X/Twitter and we will keep you updated.
