The last Nikon Z6III firmware update v1.02 made the camera compatible with the Nextorage NX-B2PRO CFExpress memory cards (see the complete list of compatible memory cards here):
Note: so far, the NX-B2PRO is the only CFexpress 4.0 (PCIe 4.0 x 2 interface) card listed on the Z6III compatibility list.
The difference between the new NX-B2PRO and the existing NX-B1PRO cards is the CFexpress standard and interface: NX-B2PRO are compatible with CFexpress 4.0 (PCIe 4.0 x 2 interface), while NX-B1PRO is CFexpress 2.0 (PCIe 3.0 x 2):
