TNA’s website was updated recently and include the following blurb on their 2014 pay-per-view events.
TNA provides its viewers with unique live Pay-Per-View events each year. Annual mainstays like March’s “Lockdown,” June’s “Slammiversary” and October’s “Bound for Glory” anchor the lineup
So it appears that they only plan on 3 pay-per-views in 2014. With the WWE Network starting up in February this could lead to the end of the pay-per-view business for pro wrestling if WWE goes forward with airing all of their pay-per-views on the network.
