@GFK: replacement 11 speed chainrings seem to be increasingly hard to find, at least in the UK. Is there a plan to replace with the 12 speed rings, and if so, how is the backward compatibility with 11 speed (and hence 10 speed with 11 speed chain).

Unfortunately i can confirm that 11speed Campy chainrings are not good for 12sp chain. Chain falls when shifting on bigger ring without being super careful. No way to adjust on EPS.

Can anyone comment 12speed chainrings compatibility with 11 speed 4arm cranks?

Thank you!

Yes, I mean these..from what i can see, when upshifting to bigger chainring chain stays on top of teeths at 12 position (maybe chain is too narrow) rarher than in the teeths..when turning cranks slowly, the chain catches ok..when turning fast or with too much force the chain falls out of the big ring. Shifting to small ring seems fine..

But that is just my observation, i don't know if it is just about proper 12 speed chainrings or you need also 12 speed cranks because there is different space between rings..

And vice versa: what is compatibility of 12 speed rings, with 11 speed chain and set up?

I like the weight boxes. They remind me of the 1990s Campagnolo boxes I lusted for.

I have used the Super Record mechanical and eps group with a Rotor 3D+ crank with so called 11spd 50-36 q - rings and with a Rotor Aldhu 3d+ crank with direct-mount 50-34 q rings without any issues.
I must admit Rotor confirmed me only the Aldhu 3d+ direct mount chainrings are 12 and 13v compatible.

Wow Merlin has the price for Record 12 mechanical groupset at $1,277.10 USD

Actually $1419 - 10% deal right now = $1,277.10
But pretty decent price
