Nah that ain't happening. Trips has a bad heart and some of his responsibilities have been reduced due to his heart ailment. I think Shane would be much worse than Vince at the top (which is crazy to say) b/c reports came out earlier this year how there was chaos due to how he booked the Royal Rumble match and how it turned out.
Honestly, I think regardless of how the investigation turns out, Vince should step down permanently or be forced out by WWE Board of Investors. It's about time some of those old heads be removed out like Johnny Ace, Kevin Dunn, Bruce Pritchard, etc, these folks have been in the company at least 30-40 yrs off & on.
