The component will be removed from two Breeze-M upper stages awaiting integration at the Russian-run Baikonur Cosmodrome
Yes, for Intelsat-23 and Luch-5B/Yamal-300K. But if I have understood correctly these upper stages will be returned to Moscow. Other upper stages will be used for these launches.
Bob Christy has reported that there are rumors that the dormant Briz-M has exploded in orbit on October 16. Note that Spacetrack's last TLE for the stage (2012-044C/38746) was issued on that day, although no debris has yet been identified.http://www.zarya.info/Gallimaufry/120707ProtonFailure.php

These have some information about Briz failures.http://www.orbitaldebris.jsc.nasa.gov/newsletter/pdfs/ODQNv16i4.pdfhttp://www.orbitaldebris.jsc.nasa.gov/newsletter/pdfs/ODQNv14i4.pdf

Remarkably, this break-up occurred just hours after the Rokot delivered the Radio Rosto satellite to orbit. Briz-K was the original version of the upper stage, apparently developed as a propulsion system for the Naryad ASAT system.
