LEGO had announced that the retirement of 10232 Palace Cinema on their official Facebook page:
Don’t miss the last screening at the Palace Cinema before the lights go down for the last time. This icon of any modular street corner will be retired soon; so get your tickets for cinema classics like Forever Sorting and The Brick Separator now.
We have predicted that Palace Cinema will be retiring this year. This set was first released in March 2013, a four-year life span. This is the oldest Modular Building set that still available in the market. So if you are planning to buy this set, you should act fast now!
Thank you, Fabian and Hayo for the tip!
