According to Brickfinder on facebook, the new Creator Expert Modular will be revealed on the Singapore Comic Con 2019. The Singapore Comic Con happens on 7-8th december 2019. So it seems that we’ll have to wait until the weekend to get the full reveal. This places the reveal a couple of days later than last years reveal of the Corner Garage 10264 – it was revealed on December 3rd 2018.
Personally, I’m excited to see what they new modular will be! Do you have any guess?
EDIT: The LEGO group does seem to have a stand on the Comic Con 2019. It’s on the floor plan of the Con – stand B25.
