WWE would be fucked up for a year plus if Vince died without much warning.
And as much as people here say they hate the guy and have wished things on him even I won't wish on people I don't like, the day he goes will have everyone saying how they already miss him, wish he hadn't gone, etc.
I really hope he turns out okay. Vince, with as many boneheaded moves he may make, knows the business better than any other person alive.
