Bret Hart came back. Shawn Michaels is retired. Randy Orton is a good guy. They brought up a bunch of guys from their developmental for a show called "NXT". 7 of the 8 "competitors" from the first season of that show attacked random people on Raw, tore up the ring, left John Cena laying, and formed a group called "Nexus", which has been the big storyline of the past 6 months.
