Do we know if this launch will use an upper stage, such as Volga, or launch with no upper stage?
If not, when do we find out--when the LV is rolled out to the pad and images are released?

The Volga stage will presumably be hidden within the payload shroud, so it won't be visible.

From what I have found, I think the first six rockets had associated Volga upper stages. The initial five are part of one contract for the Russian military. The sixth was for Lomonosov satellite.

The Russian launch schedule thread lists this one as scheduled for this week. Has there been any indication that it is holding that schedule? Has anybody seen any NOTAMs that could indicate a launch is close?
Anatoly Zak has it listed now on his site in the first quarter after Soyuz MS-08 due to ongoing payload issues although he does not yet call it EMKA. He foresee's no launches until February at this time.

Anatoly Zak has determined that EMKA is actually a Spacecraft Platform for the MKA programme and not the name of the Spacecraft flying:

That would be confirmed by the fact that the VNIIEM annual report for 2016 (mentioned earlier in this thread) talks about "a satellite based on EMKA". The name of the satellite itself is probably classified. No Ministry of Defense designator (like 14F...) identified yet either.

Look back at the earlier posts: remote sensing satellite “on the basis of an experimental small space apparatus" (EMKA)”.
http://forum.nasaspaceflight.com/index.php?topic=44139.msg1753080#msg1753080

Mr. Zak has done this before, during the 1st Bars-M launch for example. Contents of his website are edited or changed but you can already find details in the NSF.

There could be a link between EMKA and two small high-resolution remote sensing satellites described in the 4/2014 issue of the VNIIEM journal "Voprosy elektromekhaniki". One is called "Zvezda" ("Star") and the other MKA-V (MKA standing for "small satellite" and "V" for high resolution). Zvezda is described as a technology demonstrator for MKA-V. Zvezda is a 150 kg satellite in a 300 km orbit with a maximum resolution of 0.5 m and a minimum lifetime of one year and MKA-V is a 250 kg satellite in a 450 km orbit with a maximum resolution of 0.6 m and a minimum lifetime of five years. VNIIEM was said to be wiling to launch Zvezda in the first quarter of 2015 without any government funding in order to pave the way for MKA-V.  More details (including a drawing of MKA-V) here:

http://jurnal.vniiem.ru/text/141/17-22.pdf
(see p. 18-19)

Zvezda/MKA-V were apparently presented here as civilian remote sensing satellites, but might just as well be used for military purposes.

Zvezda is also mentioned in a paper given by VNIIEM specialists at the Korolyov Academic Readings in January 2015. Here it is described as a 200 kg satellite in a near-circular 500 km Sun-synchronous orbit with a minimum lifetime of 5 years. The paper focused mainly on the selection of orbit correction engines for the satellites. The authors say that the choice had fallen on the hydrazine-fueled K50.-10-5 thermal catalytic thrusters of OKB Fakel (also installed on NPO Lavochkin's Kosmos-2519 satellite).
