Predator can hit termination as early as 2022 assuming the Thomas Brothers have begun working on a notice. They can't just take it, they do have to let all I.P holders know what's up before the termination date specified in the notice (this might get a bit complicated as it comes to merch like comics but I could easily be wrong). They have a very short window to serve that notice as well since according to the site I'm getting my information from, they need to have it two years before 2027.
I'm not 100% convinced they will but you never know. If we've only just now heard rumblings about this and it's just that Predator could be terminated I think we're fine unless something really disastrous happens.
