How much longer will Ninjago go on?

Edit: I’m only on S3 of DR so please no spoilers, thank you I’m usually not a fan of spinoffs, animation changes, new main characters, etc. BUT - I honestly really enjoy Dragons Rising. Sure, it’s not the same as it used to be, but it’s not bad either imo. I like it. Now, I’ve seen different rumors about how many seasons there will probably be, most people say either 5 or 6, and yeah, I know everything has to come to an end eventually. For example, I think the MCU didn’t need ALL those extra...
