Normally at this time of year, "Y2J" Chris Jericho normally comes onto our screens and produces some kind of excellent match at Wrestlemania whether it be with CM Punk, Fandango or Christian.
However, The Wrestling Observer have stated that this year Chris Jericho isn't coming back at Wrestlemania for one major reason. Normally, you hear reports of "differences in money" or "injury picked up at the last minute". However, Jericho reportedly didn't come back due to "creative issues".
This was reportedly back late last year. WWE's Creative aspect has come somewhat under fire recently with decisions with "certain" superstars so it's not impossible to think that Jericho had more issues with a creative return. The other side of this as well is that he does have Fozzy to support him financially. Jericho has noted numerous times that he loves playing and touring so it's more WWE's loss than Jericho's in regards to a return.
