WWE Classics on demand is currently scheduled to expire by March 31st. Initially the plan was for WWE Classics to stop at the start of 2012 but some cable providers have contracts that require the service to be available until the end of March.
While the plan is for WWE Network to launch on April 1st, same day as WrestleMania 28, many have their concerns over this according to the Wrestling Observer Newsletter. There is a fear that a lack of clearance and planning will harm the network causing it to flop. As of now, the first day of the networks programming is scheduled almost totally around WrestleMania. There is currently no other programming schedule in place.
