The feeling is that TNA moving the Lockdown PPV to March is a sign that TNA is going to pull back on the number of PPVs they promote a year. For some time, Dixie Carter has long been vocal about not wanting to promote monthly PPVs, but couldn't change that due to existing contracts with the PPV companies.

While nothing has been officially announced, the feeling is that the change will be made.
