Noctua confirmed that the heatsink mounting on Intel's new LGA1200 platform (code name Comet Lake S) is identical to all LGA115x sockets (LGA1150, LGA1151, LGA1155, LGA1156).
This means that existing coolers from Noctua which support LGA115x also support LGA1200, out of the box, without any extra mounting kits required.
Intel is expcetd to hold a Comet Lake-S desktop processor and motherboard launch event soon. Various retailers have already provided some information and pricing for upcoming Asus, Gigabyte and MSI Intel Z490 motherboards, equipped with the LGA 1200 Socket.
Many other cooler models that do not support LGA115x can be made compatible free of charge with a NM-i115x Upgrade-Kit provided by Noctua.
So, if you are already having a Noctua cooler, the following models include a mounting-kit for socket LGA1200/LGA115x and are thus compatible out of the box:
In addition, all older models which have been upgraded with the NM-I3 kit can also be used on LGA115x without any further upgrades.
The following models can be made compatible with the LGA1200 socket free of charge using the NM-i115x upgrade-kit:
The following models can be made compatible with the LGA1200 socket using the NM-i115x upgrade-kit but are not eligible for Noctua‘s free mounting offer, so users have to purchase the kit at local resellers:

NH-U9DO (Note that the A3 version is not compatible)
The following models are not compatible with the LGA1200 socket and can not be upgraded:
