If John Morrison doesn't get that main event push now then he never will. Through some good luck, this is the best chance John Morrison will have to solidify himself as a main event superstar.
Just look at the scenario. Chris Jericho is on a hiatus, CM Punk got traded to RAW and then gets injured soon after that. When Triple H returns he will automatically be put into a feud with Sheamus through default and you would have to think that if Randy Orton loses to Wade Barrett then he will not stop until he makes John Cena pay.
This in theory will leave the would-be champion Wade Barrett without a challenger for his title if HHH is feuding with Sheamus and Orton and Cena are trading blows. Although the Miz is there, WWE is unlikely to do a heel vs. heel match at a PPV.
This leaves John Morrison with the chance to be able to face Wade Barrett at a future PPV, but then his main event push needs to start at Survivor Series. Morrison needs to win at Survivor Series for this to happen. Should he lead a team to victory then I believe that John Morrison will definitely be a world champion by 2011.
