The Rock responded to John Cena and met him face to face in the ring.
In total, from Feb 14, 2011 to Mar 1, 2012, The Rock has made 11 fresh appearances on WWE TV (not counting the WrestleMania 29 Press Conference and vignettes of The Rock attending movie premieres, visiting his high school, etc). Eight of those appearances were live, 3 were taped.
That's 11 appearances in 12 and a half months, which averages out to one appearance every 1.14 months. Rock has appeared live once every 1.56 months and made an address “via satellite” once every 4.17 months.
The most glaring statistic is the number of taped appearances by The Rock -- John Cena has started a hash tag on Twitter about Rock's lack of being in the arena: #TeamFilmIt. In reality, it's the combination of some taped appearances and the amount of time between appearances that creates the illusion that Rock is always “via satellite” -- even though that may not entirely be accurate.
Aside from that, based on The Rock's habits in the past 12 and a half months, we can confidently hypothesize that he will grace us with his presence on WWE TV about once a month, with the frequency picking up leading up to a pay per view matchup that will typically be announced well in advance; evidence of that includes announcing he was the guest host of WrestleMania 27 two months prior, booking his match with John Cena for WrestleMania 28 a year in advance and announcing at the WrestleMania 29 press conference recently that he will take part in that event as well.
Is this frequency enough for The Rock on WWE TV? I say yes, for many reasons. First, The Rock has nothing left to prove. I agree with the train of thought shared by the likes of Chris Jericho (said on The Rock's latest DVD release) and Lance Storm and Shane Helms (on Twitter): The Rock has absolutely nothing to prove in pro wrestling. He paid his dues and travelled the roads countless times, doing exactly what John Cena says he isn't doing today during the Attitude Era in the late 90s. The Rock is good business for WWE and many who complain about his position on the card might certainly be jealous or could not fill that role currently themselves.
On the flip side, a different reason I'm fine with The Rock staying away for periods of time is because I'm already starting to remember why I got tired of The Rock in the first place – The Attitude Era, as successful as it was, was also the era of overbearing repetition. Even with new catchphrases and techniques, The Rock has already become stale in certain areas. For example, the “(insert phrase here)? Trending on Twitter Worldwide!” game, despite it's effectiveness, is already played out – not to say The Rock (or, as John Cena would tell you, “Brian”) won't be able to think of more funny material, but that time is rapidly approaching.
One thing is for sure – The rivalry between John Cena and The Rock seems genuine and personal, and with both of their fresh verbal skills (even if The Rock writes some cheat notes on his arm), we are in for an entertaining final stretch on the “Road To WrestleMania”.
