Does such a thing exist? Noticed Rachel Atherton's DH bike had Saint badged wheels which looked OK (hoping they'll be like Deemax's but half the price…). Google doesn't help much though so guess either prototypes or rebranded wheels from someone else.

They do exist, I have seen a set. However they are not in production for general sale, they are just for certain sponsored riders.

Seem to remember reading they were just rebadged but I can't remember where or who makes them. Not much help, sorry.
