Emmmmm did you see the tag match at Survivor Series? The Rock looked great and he was wrestling pretty dam good too! He even busted out some moves we hadn't seen (at least I hadn't anyway) from him before (fisherman's suplex, magistral cradle).
Comparing the physical condition of The Rock in 2012 to Hulk Hogan in 2002 is silly, and a little unfair to Hogan to be fair.
Hogan was nearing 49, his body was very broken down and I'm not too sure how long he had to get into shape before he made his WWE return.
Rock on the other hand is nearly 40 and has had a full year to get himself in the best shape of his life - not to mention he's not got any injuries from years and years of working matches on his body too.
Wait 'til we see the match, Rock will definitely be able to go, definitely.
yeah...I saw the Rock in a very controlled environment, for a few minutes only, nothing remotely similar to what his match with Cena will be. I also remember Hulk Hogan being the top heel of WCW only a few years prior to rejoining the WWE. I also remember Hulk Hogan becoming the last ever WWF Champion a month later. (renamed to WWE Title due to World Wildlife Foundation bullshit). I remember him winning the Tag Team titles with Edge that summer, and I remember Hulk Hogan beating Vince at Wrestlemania XIX (20+ minute match) too. He was an active wrestler for the next full year after Wrestlemania X8. So, for a guy who was supposedly broken down, it's obvious that in 2002, Hulk Hogan still had plenty in the tank.
