So looks like there will be 3 flavors of OSSC products, plus some expansion boards and a new proper remote.
OSSC Pro
Expected price? Under $500

due to components shortages, but will be reduced once things normalize.
I was expecting 4K upscaling at $500
OSSC Pro Expansion card
"This card provides an analogue video output (not currently soldered on this early prototype) and a digital audio output. Ideal for streamers or speed runners who want to stream content to a capture card while playing on a classic CRT monitor. It’s also great for people looking for an easy way to take advantage of the OSSCs downscaling capabilities without needing an often expensive HDMI to VGA converter."
OSSC Classic 1.7
OSSC Dexx-vd ISL (for the DE10-Nano MisterFPGA)
Expected price under $50, market permitting.
Proper Remote
Definitely some exciting stuff!
