This seems to suggest that WrestleMania would be the only event not offered as part of the WWE Network package. Pay Per View events would still be made available regardless of a subscription purchase. Other programming mentioned included the Monday Night War, new and classic programming and repeats of RAW and SmackDown. WWE is scheduled to hold a conference call on 2/28 to report the company's fourth quarter earnings and Vince McMahon had promised more details on the WWE Network then.
UPDATE: To follow up on DirecTV issuing a survey to subscribers, price points for the network were also tossed out. Pricing included $12.99, $14.99, $16.99, $19.99, $24.99 or $29.99.
The point of the survey was to gain feedback on if people would commit to a subscription and how much they would be willing to pay per month for it. As also noted last night, the monthly subscription price would include 11 out of 12 Pay Per View events (WrestleMania would remain a one price only event) along with new content.
More details are expected on 2/28 during the WWE conference call.
