In "Ok, someone else realized these movies were getting repetitive as fuck," news, Warner / WAG is apparently giving up the license to make movies based upon the bricks.
The characters created by Warner Animation Group in their movies "The Lego Movie", "The Lego Batman Movie", "The Lego Ninjago Movie" (Which the source didn't even mention), and "The Lego Movie 2" would remain at Warner.
Whatever studio gets the rights would make an entirely new LEGO Cinematic Universe.
This is rumored to be based upon a green light deal that didn't happen. Movies in the LEGO universe unmade at WB include "The Billion Brick Race".
