CM Punk has been on fire for the last year! He was injured for a few months, so they put him on the announce team and he was brilliant at it. He announced NXT Season 3 and just completely tore the show to pieces (in a sense that the show was crap, but him mocking it made it awesome).
You obviously missed all the excitement with the Nexus too. Bit stale and drawn out at the moment, but when they debuted they went after Cena, and for the first few weeks just kept invading during matches and tearing shit up. The first attack was incredible.
