1) A new season for autumn 2019 is already in production. That’s right. Jodie has been renewed for another series. Eat it, White Male Supremacists. Chibnall is coming back as well although a rumor says he will leave after season 12 and that Whitaker may (or may not) go with him. Chibnall turned down showrunner once and said he never wanted it in the first place.
I wasn't aware of the internet rumours, as I long ago decided that "the fandom" (insert vomit icon) was, if not toxic, incredibly dull; and have devoted my life to avoiding it all costs.

So this news gets a mild, but palpable, yay from me.
