Cue "SHUT UP AND TAKE MY MONEY!" memes.
If you have a 360, ps3/4, or roku you'll also be able to watch it on your TV. The first live PPV available will be WrestleMania XXX so they're definitely going to have incentive to make sure their infrastructure is up to the task.Ten bucks a month for the PPVs on iOS rather than $50+ through television PPV? Nice. Access to all past PPVs anytime? Good. Access to all archival footage? Good.
This would do well, I think, if their servers are strong.
WWE PPVs have been available for purchase digitally before, I've never ordered one direct like that so I can't say how well it worked.
