The LEGO Ideas Review Board have finally announced that the next set of LEGO Ideas projects that will go under production are to be announced tomorrow morning. Some of the projects under review have been on the site since as far back as 2018 and as recently as 2020—when the Third Stage of 2020 closed. In total, there are 25 projects up for review, and there are currently six LEGO Ideas sets in production: The Earth Globe, Fender Stratocaster, Seinfeld, Home Alone, Sonic Mania and Vincent van Gogh: The Starry Night. Also, just to put things into perspective, the LEGO Ideas Second Stage 2020 Review Phase only resulted in 1 out of the 35 projects being selected—so it's unclear whether the current backlog of Ideas Sets (which stretch back to 2018), along with the fact that the most recent review only resulted in 1 set making the cut, implies we'll only see one more set added to the fold.

Our Thoughts
A few key points to note on which sets will almost certainly not make the cut are Boeing 737 Passenger Plane, Colosseum (Architecture Style), and Brick Town Police Station. This is due to the fact that we've already gotten Official sets in the form of LEGO City Passenger Airplane (60262), Creator Expert Colosseum (10276), and Creator Expert Police Station (10278). Also, projects like Open MRI, TX Master Games, Classic Castle, and Red Dwarf Starbug just lack the complexity and wider appeal of many of the other sets, so it's very unlikely they'll be selected by the Review Board as the next Official LEGO Ideas Sets.

Some repeat 10k Club Members are Disneybrick55 (The Addams Family Mystery Mansion), whose previous project The Earth Globe is currently in production; Bricky_Brick (The Car Wash/The Little Venice), who has submitted a multitude of projects and was the Project Creator behind the LEGO Ideas Pirates of Barracuda Bay (21322); and BrickHammer (Viking Village) who is also a prolific Project Creator, and who has several projects launched on the site currently and has had several projects reach the 10k Support mark in the past.
Some likely candidates for selection would be the Auto Union Type C Racecar, which is similar in format to 2016's LEGO Ideas Caterham Seven 620R (21307); Motorized Lighthouse, due to the uniqueness and additional functionality it poses; and Avatar: The Illuminated World of Pandora—which would strictly be selected due to the fact that LEGO and Disney have had a very lucrative history working together.
Some of the top picks for selection in the review phase would be Avatar: The Last Airbender, Bag End, and Jumanji 1995—and the reason for these selections is that they're the most intricate and most niche-oriented selections. The only reason these may not make the cut is due to IP or licensing related issues. We know based on the history of LEGO having produced Lord of the Rings sets and Avatar sets, both of which fell relatively flat on retail shelves at the time, have since seen astronomically high resale prices on the aftermarket, mostly due to a resurgence of nostalgia from millennials who otherwise may not have been able to afford those sets at the time they were widely available for retail purchase.
