Gan are soon releasing a Gan 11 M and Air 3x3x3, these appear to simply be variants on the 11 M Pro/Duo series. The 11M will be a cheaper version of the Gan 11 M Pro without the interchangeable magnets or the core-corner magnets, making it very much like a standard magnetic 3x3x3 but with Gan's 11M base design. The 11 Air appears to simply be a non-magnetic version at a lower price which might be nice for some people who want to magnetize it themselves or do not like magnets at all.
