sealed cartridges? I'm not sure if that precludes the presence of cones
He was using 'cones' as short hand for 'bearing retainer nuts'. Novatec run the bearing inner race directly on a shoulder on the axle, some cartridge bearing hubs do actually use something which looks kind of like a cone (but with parallel sides) to create the seat for the cartridge on a threaded axle, like this:
To answer your question I have bought 4 of the MK2 and a some MK1's in the past, and the MK 2 all came as fixed/fixed. They look and feel really nice though, a fair bit nicer than the MK1's in my opinion (sturdier feel with fatter, better looking cones, smoother feeling bearings).
