Can we drop this subject already? This is about the millionth post I've seen on this subject over the past year.
WWE is NOT going back to a TV-14 rating, because they have deals with companies like Mattel and others that would only license them if they were kid-friendly. Not to mention the concussion discoveries over the last few years that keep them from doing certain chair shots and even them going so far as to banning Randy Orton's head-punting move. Also, all of the issues with Hep-C that prevent bleeding during matches, as well as the Benoit debacle and Linda McMahon's political aspirations. All of those things and more have changed the course of the company forever.
They are a publicly traded company who has to answer to investors, so they are going to be careful about everything they do (see Chris Jericho's suspension). Sure, they carry an edge every now and then (within the constraints of the PG rating), but the days of the Attitude Era are DEAD AND GONE! Get over it, please, and move on.
