According to information that I have collected, this is the last flight of the Molniya-M/2BL, and, I believe, the last Oko spacecraft launch.
After this, only two Molniyas will remain, both M/ML configurations, and both scheduled to launch Molniya spacecraft next year.

My information if from inferred sources, so if it is inaccurate, please let me know.

There will not be launches of Molniya satellites more in future... These satellites are not produced already for a long time... The last launch (failure) of Molniya (Molniya-3K No. 12L) satellite was on June 21st, 2005... Meridian satellites performs functions of these satellites now...

So what will Russia do with the two remaining Molniya rockets? Gunter's launch schedule has them slated to launch Molniya spacecraft.

Shortly after the last Molniya 3K launch failure there was an official announcement from a governmental source saying that "a replacement satellite will be built and launched within a year".

August 2007 passed, but a new Molniya 3 satellite was not launched. I wonder why they developed an upgrade to the Molniya 3 series, but only produced a few Molniya 3K satellites.

However, it seems that at least the Molniya 1T series was terminated in favour of the novel Meridian  satellite. Usually, the Russian military keeps one or two satellites of the outdated type in reserve in case the new design does not work properly and has to be improved.

I am almost sure that this is also the case with Molniya 3K. But for financial reasons they could have decided not to launch them or only to launch them in case of a premature breakdown of one of the orbiting satellites.

I assume that a second Meridian completing a minimal constellation of two spacecraft will only take place after the careful examination of the engineering features of the prototype spacecraft.

So are we saying that this launch will mark the retirement of the Molniya carrier rocket?

Conditional, if the current system needs a speedy replacement, or the Meridian system isn't working as it was supposed to, then you might see another launch. But if things run their normal coarse, the Oko and Molniya satellites will be withdrawn from service, and their replacements don't need a dedicated LV.

There are no spare Molniya satellites more...

According to www.novosti-kosmonavtiki.ru the launch seems to have been successful and Kosmos 2430 satellite was put into orbit

Bump for Kosmos 2430 reentry:

Quote
Russia’s Aerospace Force Command revealed that the Russian Kosmos-2430 military satellite was deorbited Jan. 5, then burned up over the Atlantic Ocean. The satellite was excluded from the orbital grouping in 2012.
