Su-30 is in active development. devs are currently adressing some bugs regarding CWS and new MFDs and i think that there would be announcment of some kind if ka-52 was canceled or postponed
would it be possible to add russian and us subs with kalibr missiles for russian side and tomahawk missiles for us side?
or would it be possible to retexture tu-95sm/tu-160 and add some more cruise missiles?
