I'm not sure what was the occasion, but the Rocket Forces confirmed the plan to deploy four silo-based Topol-M missiles in Tatishchevo by the end of 2011. But no actual deployment has happened yet - traditionally it happens in December (old habits of the Soviet planned economy die really hard).

So far everything goes according to the plan first outlined in December 2010 - four silo-based Topol-Ms in 2011 and four more - in 2012. All missiles are expected to carry a single warhead.
