It will honestly depend on the Season 13 finale, if they introduce a whole new Big Bad or concept then I'm pretty sure they're going for another couple of seasons but if it feels like they're about to close the storylines then yes they might end it with Season 14.

''If not, I might stop watching after Season 13, coz they keep putting unnecessary hiatuses in the middle of the seasons, plus the show's been going on for too long. Buffy stopped at 7 (with five seasons of the spinoff Angel), Charmed stopped at 8.''

I disagree with this part. Hiatuses are expected, there is a schedule and if hiatuses don't exist, shows will all end their seasons in just a few months. Speaking of, the number of seasons don't usually tell the show's overall quality. Yes, there are a lot of shows where it gets crappy after 3 to 4 seasons (Glee, Teen Wolf and The Vampire Diaries to name a few) but in Supernatural's case, the writers give us something fresh every season which is very impressive. I was going to stop after Season 6 or 7, I think, because I felt like everything went to sh*t but then Season 8, aka one of the best seasons, pulled me right back in.
