#3 Could have fallen behind: New challengers have appeared

After the end of the much ballyhooed Monday Night War, in which WWE bought out their biggest rival WCW, they enjoyed about ten years of relatively little competition.
Even their next biggest rival, TNA Wrestling, failed to garner even a fraction of the WWE audience. They were able to split themselves into two separate brands (three if you count the short-lived ECW revival) and basically had a wrestling monopoly for a decade.

However, things have begun to change. Cody Rhodes and The Young Bucks have catapulted their All In event's success into talks of beginning their own wrestling promotion. In fact, Cody has been spotted at the Jacksonville Jaguars stadium in the owner's box, and their LLC has been registered at that address.
Add to that the fact that Ring of Honor and New Japan Pro-Wrestling have managed to sell out Madison Square Garden--the heart of WWE territory--and are presenting a real challenge to the WWE, and it seems like the promotion might be in for some troubled waters.
