The four sets are 41634 Emmet, 41635 Wyldstyle, 41636 Benny and 41637 Sweet Mayhem, each using a mix of techniques and printed pieces to represent the film characters. Part way through the video, the new sets are announced.
Given that the rest of The LEGO Movie 2: The Second Part range has already been released, it did not seem certain that these sets would still be coming. According to the video, they have already been launched – which they haven’t – so the release date is not yet known. The next date that new LEGO sets are expected to be released is March 1, so they may arrive then.
The LEGO Movie 2: The Second Part will be released on February 8, 2019.
