Renewed! (Though it's unclear whether this will be a full season or a miniseries or even a one-shot special as happened with Sense8.)
Three books, right? I understand part of book three happened already but they made it sound like it'd be 3-4 seasons.
Netflix usually gives some indication of the size of the renewal when they announce a renewal. They gave no such information this time with 3 Body Problem, which is what has led to speculation that it will be a reduced/short order.
