true but the rock is able to come back if he wanted, austin cant wrestle anymore due to neck injury although one last match is possible depends if it gonna make the money for his last match, they wouldn't give him a last match to face someone like matt hardy or scotty 2 hotty....it would be someone like goldberg, taker, hogan, brock lesnar....etc.
as for guys like taker he still wrestling but not every week, jeff moved on cuz he turned up late to work too much.(thats what i heard) and well at the end of the day none of them are immortal so they do get injured forcing them to retire or get old so they retire..........thats life things change luckly when hulk hogan left the company bret hart took the mantle then hbk then stonecold/ the rock and now batista/john cena.
i guess you have a fav wrestler then u adapt to the next one...i like stonecold but when they took him through the alliance and turned him into somethin that he was'nt (running from kurt angle...........tapping out to ankle lock) that was'nt stonecold they dragged his character through the mudd................but he was brought back to who he should be the bad ass..............i like john cena at the moment and batista also chris masters he is a future champ give him a few years....
