Brickset members group member Larry L has spotted the 71741 Ninjago City Gardens set promoted in a copy of the LEGO catalogue that he received by mail in Canada.
Rumours of this set has been swirling around for at least a couple of months ago as a celebration of the 10th year anniversary of Ninjago and an extension to the original 70620 Ninjago City and 70657 Ninjago City Docks.
It will have 5,685pcs and will feature 19 minifigures (including the 10th year of Ninjago collector series Golden Wu)
The set will go on sale on Jan 14th 2020 for LEGO direct VIP members and Feb 1st 2020 for the rest of the world.
Thanks to Larry L from Brickset members FB group for the pictures.
