The Buran/Energia project is long dead and buried. The Buran orbiter which made an unmanned flight in 1988 was destroyed in 2002 when its hanger roof collapsed. Even if Russia could resurrect Buran I doubt that they would. Buran has a very similar heatshield to the US Shuttle and Columbia demonstrated the problem with that.
Russia is currently planning a successor to Soyuz. Initially it was going to build a small re-usable winged vehicle called Kliper. Looking like a mini-shuttle it would have been launched on top of a next generation derivative of the current Soyuz launch vehicle. It was hoped to build this vehicle with the cooperation of the European Space Agency. ESA, however, has refused to help fund a winged vehicle. Russia is currently deciding whether to go it alone with Kliper or develop a capsule based spacecraft in conjunction with Europe.
The Americans will retire the shuttle in 2010. The replacement, currently known as the Crew Exploration Vehicle (CEV) will fly sometime between 2012 and 2014. Eventually America will use the CEV to return to the moon.
Two new launch vehicles will be developed. The Ares I will launch the CEV and the Ares V will be an unmanned heavy lift vehicle that will eventually be used to deliver the new moon lander to Earth orbit.
