Well the thing is, maybe it would inspire networks to come up with their own shows?
I bet there's a lot of networks/leagues looking at the WWE and seeing what will happen. The smartest thing the WWE did was require a 6-month commitment. This prevents people from just paying $10/month to watch Wrestlemania and then cancel. I saw that last year, the WWE had a million people buy Wrestlemania. So if they can get a million people to sign up for this, they will be raking in the money. You're basically paying $120/yr, which is what the cost of 2-3 PPVs? I can't think of any reason a WWE fan wouldn't sign up for it.
