The architecture firm Populous (nee HOK Sport) is now in the process of designing and building two Olympic stadiums. This design for Sochi, the winter games in 2014 was just unveiled. taking hints from beijing much?

Their design for the 2012 summer games in London is perhaps less flashy, but more praiseworthy for its sustainable approach. The stadium will seat 80,000 people for the games, then be deconstructed to a more reasonable 25,000 seat venue, more likely to achieve permanent occupancy.
