Following TNA's announcement on Thursday that Lockdown will be held in March of next year rather than April, a lot has been speculated about the company's future on pay-per-view. Dixie Carter has publicly said TNA was looking to reduce the number of pay-per-views they did each year.
In May 2012, Carter said (comments here) she doesn't feel the company needs 12 pay-per-views a year and that they were negotiating their pay-per-view contracts. When asked about the ideal number of shows, she said six to eight was a possibility.
The general assumption is with Lockdown being moved up that shows are going to be nixed in favor of the new format. The move didn't happen this year as TNA was already locked into contracts with cable and satellite providers.
