The Series End Teased
I saw an "article" online about Season 14 being the shows last season, you know the whole "we want to make it to 300 episodes and then they might be it for us"
Now another "article" was posted about "season 15 confirmed" I guess Jensen and Jared said they want to keep going regardless if they make it to a 300th episode.
Maybe it's because of the Wayward Sisters spinoff announcement that has "some people" worried that they want to stop/quit.
