The (still unnamed) cooler from Noctua is expected to weigh around 1.5kg and will be able to passively cool a processor with a TDP of up to 120W. Last year the firm showed a prototype with 1.5mm thick aluminium fins and six copper heatpipes.
On a related note, we also just learned that Noctua will introduce white fans in Q2 2021. Towards the end of 2021, the company plans to release a next-gen version of its NH-D15 as well as an updated 140mm fan.
