Soyuz is currently sitting 1,894 launches according to the Starsem website. Will it make another 106 launches before it is retired?

What if the replacement launcher is called "Soyuz"?

Opened up that can of worms pretty quickly. Contrast Soyuz with another legacy LV, have other NSF polls counted all members of Atlas family under the blanket term "Atlas" wrt total flight rate?

Change the initial question to "R-7 derived" and I think it works. A Zenit-derived Soyuz would not count.

At least 585 flight...not bad...

The tally of 1,894 launches is because you include launches of the R-7 ICBM version. If you leave out all R-7 ICBM launches, then you end up with over 1860 orbital Semyorka launchers. So if there's 101 launches left (see https://www.sworld.com.au/steven/space/russia-man.txt), then the Soyuz rocket won't make it to 2000 launches.
