It’s definitely not the MegaFM, it has much more sliders…, the buttons say:
The LED matrix in the beginning looks like from their Octopus sequencer module.
My educated guess…it’s 2x that Soundblaster Yamaha FM chip mentioned above plus Octopus sequencer, with many sliders in a box. A MegaFM Mk2 maybe, that can be used as FM drummachine, as mentioned above? Very interesting …!
Looks like a 6 operator MegaFM - if in any way possible…?
If he used the YM262…it’s only 4 Operator FM.
Right but it was the 6 sets of faders in the video I was referring to. Could be for something else though.
Multistage envelopes?

and the slightly tweaked version:
Haha, nice.
“Zoom in… Enhance…”
Can definitely see: bd, sd, tom, ch, oh, cym?, synth?, synth?, synth?, synth?
Looks like a drum machine 
And song controls – it’s a groove box!
Oh how interesting!
Yep, FM drummachine. 8 Tracks. Nice!
Companion for M:C.
An FM drummachine or groove box with both synth and drums?
Looks like it’s both. I wonder where that LED matrix is and if they really included Octopus features.
There seem to be only a few FM Algos. Reduced compared to the Mega FM.
5 vs 8
Thread set to: Tracking
Looks like it might have 10 tracks. Hopefully!

If you haven’t heard of Ken Shirriff, he has some amazing videos on YT (and CuriousMarc !)
Yeah from looking at it now I think the octopus may have just been used as a prop in the promo video, considering you see other eurorack stuff in the second shot.
anyway you’ll notice the lines above each set of sliders connect between ‘bd carrier’ and ‘bd modulator’ which makes sense…but then ‘snare’ and ‘bass tom/? ?’ are each separate (also not sure that says ‘bass’ before tom…the text after is maybe oh/ch? just guessing). then the synth op1 -4 are all connected with that line above them. i’m assuming this means something but maybe not? first thoughts are that there are 4 ‘voices’ at all times…a bass drum voice, a snare voice, a tom/others voice, and a synth voice. given this is based on some chips as mentioned above, perhaps each is one chip? (idk how that works tbh).
already into speculation out of my depth so i’ll shut up and post for now 
maybe some of y’all are seeing the rest i couldn’t make out
Cymbal ?
121221 just sounds like the release date, not the name of the synth
