T-14 is ready for mass production, it's just too expensive for the broke Russian government to buy enough of them. 3M22 unlike Su-57 has actually achieved it's goals. It has already been fired from ships and hit targets while achieving it's speed and altitude goals. Su-57 has not been able to achieve it's goals of being stealthy or being reliable so there is no reason it would be readied for mass production.
