Earlier today on Twitter, John Cena discussed tonight’s WWE Summerslam PPV in Los Angeles and seemed to drop a rather cryptic message. Cena added, “CeNation. Staples Center is somber, quiet. Calm before storm. I feel nervous, on edge. I want to thank everyone out there who has supported me over the years, as I feel this is one of the most important days in my career. In closing, I will say that if you do not watch Summerslam tonight, you will be missing an epic day in WWE history.”
