Released today as part of a new LEGO Star Wars line, the two set are both already marked as sold out on the UK version of LEGO.com. Both sets are inspired by Star Wars: The Clone Wars, specifically the final season that recently streamed on Disney+. They are still available on Amazon, although stock of 75280 is already limited there too to third party sellers.
75317 The Mandalorian and The Child, 75286 General Grievous’s Starfighter, 75284 Knights of Ren Transport Ship, 75291 Death Star Final Duel, 75293 Resistance I-TS Transport and 75288 AT-AT are all still in stock.
75280 501st Legion Clone Troopers was driven by fan demand, with thousands of comments on social media leading to the LEGO design team responding and coming up with a set featuring new 501st Clone Trooper minifigures.
75283 Armored Assault Tank (AAT) might not immediately seem like the most exciting set, but it includes the first Ahsoka Tano minifigure in years as well as a 501st Clone Trooper with the Ahsoka helmet markings.
While the sets have sold out within minutes, they will likely be back at LEGO.com before long.
