According to The Wrestling Observer, the investment community is reportedly regarding the comments made by Vince McMahon in the recent Forbes article to mean he's either willing to sell WWE, or at least a majority stake in the company. The idea is Vince would structure a deal that would see him remain in charge of WWE's operations, but monetize his ownership value for his family before he dies.
The investment community feels McMahon should recognize the need to strike a deal in which he can retain control of WWE, but also have the company in the hands of someone who can create a suitable successor for him. Even if McMahon sells an ownership stake in WWE, the feeling is nobody would actually replace him as the guy in charge, unless he reaches an age where he can no longer perform his duties on a regular basis.
Madison Square Garden and Liberty are said to be the two media partners best suited for a situation like the one described above, but it should be noted that WWE merger talks have been denied in recent weeks by company CFO George Barrios.
