AEW does in fact have plans to hold a TNT special in early 2022 with the Battle of the Belts name.
Andrew Zarian of the Mat Men Podcast was the first to report that AEW would hold a Battle of the Belts special on Saturday, January 8. AEW President Tony Khan confirmed those plans while speaking on the AEW Full Gear media call on Thursday.
Khan says they will have the very first Battle of the Belts in AEW and that fans should stay tuned for that. ^JN

The promotion is moving its flagship weekly series, Dynamite, from TNT to TBS on January 5, 2022 in addition to the four specials a year starting in 2022 on TNT. So the first week in January will have Dynamite, Rampage, and this special.
Battle of the Belts was the name of a few shows that were co-promoted by the NWA and Championship Wrestling From Florida 1986-1986 before the CWF went out of business in 1987.
