I'm being informed by some friends in America (who also happen to be employed by a large sports entertainment company
) that the 2010 HOF is shaping up along with Wrestlemania.
WWE are trying to twist The Rock's arm into one last match at Wrestlemania. He'll be inducted into the HOF quicker if he agrees to a match with John Cena. Cena presented the idea to Vince who agreed in allowing Cena to offer the challenge publicly to The Rock - which is why a lot of news articles are coming out in terms of Cena offering this challenge.
However, part of the suggestion by Cena was that The Rock lost - which would be a bit of a sticky point in getting him to agree. However, it's understood that Cena was overruled on this point.
Now, you'll probably say 'yeh right, talk about crap rumours etc', but the same people were correct when The Rock returned for the Eugene and Coach segment, and the Diva contest which The Rock had a pie segment in.
