A whopping 105 sets carry the ‘retiring soon’ label, with many of them already out of stock. You still have chance to catch some of them before they go, though, including those aforementioned Creator Expert and Technic sets.
Other notable sets on the chopping block include LEGO Overwatch 75977 Junkrat & Roadhog, LEGO Hidden Side 70436 Phantom Fire Truck 3000 and LEGO Harry Potter 75958 Beauxbatons’ Carriage: Arrival at Hogwarts. Unfortunately, the latter is already out of stock at LEGO.com, so you’ll have to grab it somewhere else.
According to StoneWars, 21318 Tree House also temporarily carried the label earlier today, but it’s since been removed. That confusion marries perfectly with conflicting reports that the set may be about to retire, but it also might not.
