The NFL is currently embroiled in a legal dispute with the city of St. Louis over the relocation of the Rams. Reporting of that case is leaning towards the NFL losing the suit and could be on the hook for damages of more than $1B. One of the potential "payout" options would be an expansion team in St. Louis.
Along with that, there are talks of expanding to 36 teams and an 18 game schedule. Some of the expansion candidates to go with St. Louis are Toronto, London, Mexico City, and San Antonio. I also wouldn't be surprised to see San Diego, Portland, Oklahoma City, and Salt Lake City brought up in discussion as well.
