I just noticed that my local Costo has the Archer AX11000 in stock, and the boxes are labeled as "version 1.6" versus what I bought late last year, which is listed as "version 1.0".   Also the outside of the box has a bit of a difference, with the top right corner showing "Wi-Fi 6" (version 1.6) versus "802.11ax" written in the same spot for version 1.0.

Also:  Although barcodes are the SAME on both, the PART NUMBERs are different (1.0 is 0150502601 and the 1.6 is 0150603063)

Anyone have knowledge whats the difference between the versions?  They are still both V1 revision but stil there must be something there.
