what bigger stage than wrestlemania? Not that Hogan can actually wrestle anymore, but that'd be the stage.
It is unlikely that those 2 will face off at Wrestlemania. Call it a hunch but I just do not see it happening for some reason. Those 2 seem hell bent on making TNA larger then WWE so I just do not see them going to WWE.
The best thing the two of them could do to help TNA is retire. Let the younger talents take over. If I want to watch guys who can't really wrestle and aren't particularly exciting personalities, I'll stick with WWE because their production values are higher and their poor wrestlers put on a better show. TNA needs to differentiate themselves and they aren't if Sting is in the championship picture.
