As I told my brother earlier this year, the WWE will be getting very interesting for a few years with a lot of changes, because this current crop of main eventers are approaching their slow down years, for the most part. I told him to hold on for some new main event faces and experimental pushes to create that next wave of main event talent.
This is why I didn't think Dolph stayed in the limelight the past couple years because they were not searching for new main eventers yet. I think this time is different. They are slowly letting talent get over on their main eventers.
I've seen it the transition happen throughout my life time watching wrestling. I've seen the Rock N Wrestling era make way for HBK, Bret etc to them being transitioned out for the Rock SCSA etc and them for JBL, Eddie, Chris, Cena, Batista, Orton etc.
It's already happening with Kofi's character being experimented, marketed and tweaked being referred to now as "The Wildcat." Barrett's new look. Miz's face turn. The new is coming in and with talent like the Undertaker, Triple H, Rock, Cena, Jericho etc getting older the new is coming. I wouldn't be surprised in the next 5 years if Wrestlemania and or other ppvs weren't bombarded with Punk, Miz, Kofi, Sheamus, Barrett, Cody, Dolph, Sandow, DB, Ceasaro, Ryback etc and not so much Cena. Every so often a Cena.
It's too bad for talent like Morrison who left to early, cause his chance would have been here in the near future too. He could have been the next big thing.
