Man, they're up so the fifth wave of these already? LEGO Shop@Home has listed Series 5 of the Collectible Minifigures for GBP 1.99 each. Supposedly the release date was set at September 1st, but reports have started popping up here and there. Now LEGO has listed them.
Until we see otherwise, September 1st is still the release date for the rest of the world.
