Hi,
talking about the WX as anything else than a technology demonstrator is a moot point. The aim was to make a pair of traditional binoculars as good as possible with todays technology and still fit into a small and light package.
Now you will say this guy's out of his mind talking about traditional, small and light in the same sentence as the WX.
But let me explain: The WX is a traditional pair of binoculars since it is has a straight through configuration, well known to conventional binocular users like birders, hunters, military personal or navigators. It also shows an upright and correct image - this also has to be remembered as it has some implications on the construction.
Astronomy aficionados, who love extra wide fields very much, on the other hand prefer instruments with a 90 degree angle and are used to mirrored or upside down images for best optical quality.
Regarding size and weight - given the design target of extra wide field and perfect correction, the WX is astonishingly small and light. Astronomy extra wide EPs in the 100 deg class like a 17 or 21mm Ethos weight between 1.5 and 2.3 pounds each and are usually too big for binoviewing due to minimum IPD and the fact that observers tend to have a nose which needs to go somewhere.
Add to that 50mm f4ish triplet objective lenses, field flatteners and oversized prisms dictated by the upright and correct image requirement and a hypothetical instrument built from astro components would be double the size and weight.
See this link for some DIY attemps - all are significantly larger and heavier (albeit with 70mm doublet objectives) and have no field flattening and show vignetting due to undersize prisms.

On the other hand, the 9 grand asked for the memorial edition would also buy an astronomy buff a 105 or 115 Binoptics big bin with superb russian LZOS triplet optics but still no field flattening or upright and correct image... don't ask about weight and size though plus 10x and 9 deg TFOV are not an option.

The 6 grand for the normal version would easily get you a chinese made APM 120mm ED doublet big bin plus some nice extra EPs with the same lack of field flattening, upright/correct image and 10x@9deg field...
