Well in PVO SV there will be 4 different systems, by T.O. There will be a MANPADS, there will be a point-air defense SAM (Strela-10 or the new Sosna), there will be a gun-missile system (Shilka/Tunguska/Pantsyr), and there will be a tactical SAM (OSA/Tor/Morphey). If you look at the force org of an MRBde, you will see there is one tac-SAM btln, and one mixed btln where one battery is gun/missile, one battery is Strela-10, and one battery is MANPADS.What is happening is this, the R & D programs in Russia for these Anti air systems are moving forward a X 10 times the speed of manufactors out-put rate, hense the cluster-f*** myriad of different systems.
Then there is the PVO VVS, which has the former division-level SAMs (Buk family) and theater SAMs (S-300/S-400). The Vityaz, which is a mid-range SAM, should replace the Buk, the S-400 replace the S-300, and the S-500 be an entirely new asset. A T.O. structure for air-space defense brigades could be 2 btlns of S-350, 2 btlns of S-400, 1 btln of S-500, and associated SHORAD (Pantsyr/Tor). They'd probably need supporting EW/EA, and ELINT/SIGINT gear, but I'm not well enough versed in current VVS/PVO practice to comment there.
Also the MiG-35 buy has been delayed, due to lack of funds. The contract was supposed to be signed in June, for 37 aircraft.

And production has started on the first Il-478 tanker, though it's unclear whether they have a solid contract, or the MoD has simply expressed its intent to buy them.
