And NATO Better Pray ...

 ... that Russia does not demonstrate it in 404, as was the case with Oreshnik, which shook the world. 

Russia will soon make an announcement on a new weapon at its disposal, President Vladimir Putin has said, adding that trials have so far gone well. Speaking on Friday at a press conference in Tajikistan’s capital, Dushanbe, Putin said: “I think we will have the opportunity in the near future to break some news about a new weapon that we announced a long time ago.” The Russian president added that the novel system “is undergoing tests [which] are proceeding successfully.” When asked about the prospect of extending the New START arms-control treaty, which puts a cap on American and Russian strategic offensive weapons, and is set to expire on February 5, 2026, Putin expressed optimism, saying there is still enough time to prolong the accord, “as long as there is goodwill” on the part of Washington.

In the end, it doesn't matter what it will be because by that time Russia will lead the US by TWO generations of weapon systems, likely hypersonic, and there are all reasons to suspect that the new system will come, as always, in package. The rumors about new iteration of M=13+ and 2,500 kilometer range Zircon are not just rumors and even simplest linear extrapolation allows to predict with some certainty the characteristics of upcoming weapons. Moreover, as I repeat ad nauseam--keep an eye on Russia's Air Defense systems which already revolutionized warfare. New AD complexes with 1,000+ kilometer range against aerodynamic targets and all kinds of hypersonic and intercontinental ballistic missiles are coming with 100% certainty. So, get the bucket of pop-corn. 

Update: what is known about one of these systems--highly likely full operational capability for Petrel (Burevestnik) strategic nuclear cruise missile, and that means that Russia completed the breakthrough in nuclear propulsion technology for aerodynamic and, highly likely, space vehicles. Prepare, boys and girls, for nuclear space tugs, nuclear trucks and space ships travelling to Mars and outer planets of Solar System at the significant fraction of the light speed.
