As I said, after the collapse of the Soviet Union, the Russian Federation's armed forces changed their point of view in design for aircraft, tanks, and other vehicles.
So yes, in the future, the Russians will replaced basically all of their fighter aircrafts with the all new multirole stealth aircraft, the Su-50 (also known as the Sukhoi PAK FA), which will replace the Mig-29, Su-27, Mig-31 and Su-30, plus the Su-33 and Mig-29K in the Navy. The plane looks very much like a F-22 Raptor. And not many will be made (about 60 or so), so yes, Russia will change the Quality over quantity ideas they carried over from their Soviet Union era.
As for export (one of Russia's first market is, afterall, export of military material) they have designed a super upgrade of the Mig-29, the Mig-35, that has been considered in par (an sometimes superior) to aircrafts such as the Griphen, the Rafale or the Eurofighter Thypoon. The Mig-35 has, to mention a few things, a more powerful radar, fly by wire controls, in flight refueling probe, more missile pylons (and the missiles can be air to air or air to ground or air to sea missiles), and special turbines that give the aircraft an incredible capability for special maneuvers in the air (like making a 180 turn flat, without loosing altitude) while cheaper than the other fighters, Russia has yet to find someone to sell the aircraft to. (Which is strange, the Mig-35 is awesome from the videos I've seen in YouTube)
