I think seeing the S-500s in action would be more interesting, although they're not ready for deployment until 2021.

Apparently the S-500s can hit a target almost 300 miles (482 km) away (range of 600 km for anti-ballistic missile & ABM) and 500 km for the air defence. Can also detect and simultaneously engage up to 10 ballistic hypersonic targets flying at a speed of 5km per second.

Unsurprisingly, Turkey has expressed interest in buying these from Russia, but what happens with Armenia-Azerbaijan might determine whether Putin gives them or not (he might decide they're better off in Armenia's hands!)
