I wasn't sure if this deserved its own thread since while it's a confirmation, nothing otherwise is confirmed (sets, actors, etc). So here goes:
Saw this on twitter, googled it, here's the quote from the Forbes article "James Cameron Lists His California Coastal Ranch For $33 Million", dated July 8th, 2023:
Family has been central to the Camerons during their two-decade-plus stay at the ranch and it’s partly why they’re selling. The couple’s three children are “all pretty much out on their own now,” the Canadian-born director says. “And on Avatar, I’m working in Wellington and Los Angeles. And on the new Alita: Battle Angel films, I’ll be working in Austin, so it just didn’t make sense for us anymore.”
Films, plural?
