Apparently this launch has been delayed, might be in the second part of this year?

yes it appears to be delayed partly because Russian Authorities are trying to clear up Glonass-M backlog. If I remember correctly all of the remaining Glonass-M SC's have been completed and are sitting in corporations long term storage area awaiting their eventual launch onboard either Soyuz-2-1b or Proton-M.

Any ideas on how many Glonass-m are currently in storage?

So, it's either one extra Proton or three Soyuz-2.1B?

Two three sat blocks remain (Block-47 and Block-54):
2013:
July 1 three Kosmos (Glonass-M) satellites [block 47] Proton-M/DM-03 Baikonur 81/24
2014:
TBD three Kosmos (Glonass-M) satellites [block 54] Proton-M/DM-03 Baikonur
5 individual sat blocks remain
2014:
TBD Kosmos (Glonass-M) [block 50s] Soyuz-2-1B/Fregat-M Plesetsk 43/4
TBD Kosmos (Glonass-M) [block 52s] Soyuz-2-1B/Fregat Plesetsk 43/4
TBD Kosmos (Glonass-M) [block 53s] Soyuz-2-1B/Fregat Plesetsk 43/4
2015:
TBD Kosmos (Glonass-M) [block 56s] Soyuz-2-1B/Fregat Plesetsk
TBD Kosmos (Glonass-M) [block 57s] Soyuz-2-1B/Fregat Plesetsk

Glonass-K1 (confirmed through 2015):
1 individual sat block remains:
2013:
TBD Kosmos (Glonass-K1) [block K2s] Soyuz-2-1B/Fregat-M Plesetsk 43/4

Glonass-K2 (confirmed through 2015):
2 individual sat blocks are currently scheduled:
TBD Kosmos (Glonass-K2) [block K3s] Soyuz-2-1B/Fregat Plesetsk
TBD Kosmos (Glonass-K2) [block K4s] Soyuz-2-1B/Fregat Plesetsk

Glonass-KM:

Which generation of Glonass will have sufficiently low mass so that 2 may be orbited on Soyuz at a time?

Supposedly you can launch 2 Glonass-K1/K2 on Soyuz-2-1b/Fregat-M and 6 on both Proton-M/Block-DM-03 and Proton-M/Briz-M.

I do not have specs yet on series Glonass-KM.

So why are Glonass K1 being launched one at a time on Soyuz?

Primarily the fact that the 2 K1 and 2 K2 series sats are test satellites and after those all launch it was decided to implement Glonass-KM which are larger, but is much more capable than all predecessors.
Glonass-KM fully implements following CDMA channels in L1, L2, L3, L4, and L5 signal bands:
Glonass-KM Version Block 1: Civilian CDMA Bands:
L1: L1OC, L1OCM, L1SC
L2: L2OC, L2SC
L3: L3OC, L3SC
L4: L4OC, L4SC (Civilian L4 is still in development, to be implemented via a later block/series after 2020)
L5: L5OC. L5SC* (* L5SC is still in final development, to be implemented via a later block within Glonass-KM Family)

Glonass-KM Version Block 1: Federal FDMA Bands:
L1: L1OF, L1SF
L2: L2OF, L2SF
L3: L3OF, L3SF (Federal L3 is still in development, to be implemented via a later block/series after 2020)
L4: L4OF, L4SF (Federal L4 is still in development, to be implemented via a later block/series after 2020)
L5: L5OF, L5SF (Federal L5 is still in development, to be implemented via a later block/series after 2020)

Because Glonass K1 are purely test satellites and basically GIOVE-A and GIOVE-B but for Glonass instead of Galileo programme. Glonass-K1 and Glonass-K2 test series and have operational only FDMA bands which are carried over from Glonass-M and test only CDMA (Civilian Bands) which are new and operational version is slated to first fly on Glonass-KM No. 1.

This was original plan for launches back in 2007 before Glonass-KM was created which reduced number of K2 series to two All previously planned Glonass-K2 have been replaced by Glonass-KM which is slated to start in late 2015 or early 2016 at the earliest.

The other reason I know of is costly satellite launch failures.

 I know the idea was to launch two at a time, but since then they have got heavier. Can Soyuz haul two to orbit? Is such a requirement still needed considering last years launches were cancelled or posponed?

K2 is slightly heavier than K1 originally only K1 series existed; then when Russia issued order to include several additional transmitters covering new international CDMA L Bands required to be implemented worldwide by ICC via UN treaty that created for first time UN implemented standardized international CDMA L Bands for all new GNSS sat launches worldwide begin January 2014 which resulted in creation of initial CDMA Glonass test platform Glonass-K2 to implement IOC for baseline CDMA testing and regional services.  Glonass-KM is following expedited development process for its initial block of satellites to meet 2020 deadline for FOC implementation of full/all CDMA bands.

If I understand this correctly, Glonass K1 could be launched 2 at a time, but was never put into serial production because of the requirement to add CDMA, which resulted in the KM becoming the operational system; KM is too heavy to be launched 2 at a time on Soyuz.

I suspect that perhaps 4 or 5 KM satellites could be launched at a time on Proton-M, if they fit within the fairing.

Yes.

Actually based on the available that I have reviewed, Glonass-KM will launch in pairs (2 satellites per launch) aboard Angara A5/Briz-M (Block-DM once it becomes possible to fly Block-DM from Plesetsk Cosmodrome). Older information says that a single Glonass-KM can be launched via Soyuz-2i1b/Fregat-M with newer information saying two via Soyuz-2-3V if that launcher is implemented.
Latest information rules out any possibility of launch via Proton-M/Briz-M (Block-DM).

I am guessing that Proton-M is ruled out on the basis of transfer of as many launches as possible from Kazakhstan.

It is in accordance with the plan for the eventual conclusion of Federal missions from Baikonur and the pending retirement of Proton-M launcher when all missions will be transferred to other capable Russian launchers flown from other cosmodromes.
