– There was some talk within TNA that they may go back to a four-sided ring as part of the Destination America reboot but apparently they are not going in that direction.
Advertising for the New York City tapings later this month, specifically for the Lockdown tapings on January 9th, note that all matches will be held in a six-sided steel cage so it appears the six-sides are here to stay.
On a related note, there’s some speculation that TNA may be done with the pay-per-view business with Lockdown airing on free TV this year. Lockdown and Bound For Glory are usually TNA’s best pay-per-view events.
