Honestly, I think there has to be lots of Russian 5th gen envy. Most obvious is the U.S., with small numbers of a deployed superfighter that puts everything else to shame. They're crowing a lot about their shiny new SU-35's, but they have to be realists too. It won't last long against the F-22. And now there are F-35's in theatre, which puts their vaunted S-300/400 SAM systems at risk. That too, poses an extreme risk to their SU-30's and 35's.
On their border, the Chinese have declared their J-20 IOC. While this may not be a truly combat capable bird yet, it's apparently a lot further along than their SU-57. The J-31 isn't far behind, and if it turns out to be even LO (if not VLO) and affordable, doesn't bode well for their Flanker exports. Even if the SU-57 became a mature design, how many countries could afford it? The Indians might be able to, but by all accounts they're panning it.
So I think they have a lot of 5th gen envy, and someone in Russia with the benefit of hindsight is probably kicking themselves for not running with a cheaper, more capable LO/VLO design vs. the SU-57. MIG is supposed to be working on one, but seems all but incapable. Sukhoi could start over with a clean sheet design from scratch, but that's unlikely. It will be at least another 5 years before the SU-57 bugs are ironed out, perhaps 10.
At which point F-35 costs will be circa 80 million, the aircraft will have matured and at least a half dozen countries will be flying and fighting with a 5th gen mentality. It isn't looking very pretty for them...
