Andrew Zarian from the Mat Men Pro Wrestling podcast is reporting that there have been "rumblings" about a new title being introduced soon in AEW. Zarian said that it would be for a secondary women's championship.
For what it's worth, there has been an increase of women's tag team matches across all of AEW's shows so it would make sense to introduce Women's Tag Team Titles as it would give more time to the women's roster. Currently, most of the women's storylines revolve around Dr. Britt Baker's AEW Women's World Championship.
On a somewhat related note, there have been rumors about a Trio's title being introduced at some point to spotlight the three-person teams in the company. There's no confirmation on when/if those titles will be introduced.
