I called Diamond-S yesterday. They just got a sled last week and are testing their prototype now. I was basically told they don't have a date set but was left with impression that some will be showing up early January. The stock can on the boost is pretty quiet and heavy I am pretty excited to get it off but still think Diamond-S is going to be worth the wait. I would probably put a Bikeman on if they were to put it in the mail for me today though!I haven't talked to Diamond-S directly, but Burandt has commented a few times on the NA Matryx Diamond-S release video that the boost version is almost done, just going through some final on-snow testing. Should definitely be this season, I would guess early 2022.
