I’m still rather confused whether this is an actual teaser or just a social media post to hype up season 4, so let’s examine the “evidence” we have so far (or rather lack thereof, as this is mere conjecture ):
If this wasn’t a product teaser, it’d be the first time they did something like this (that I’m aware of)
Directly advertising the current set would make a lot more sense if a new one isn’t planned as they must be aware what most people think when they see a teaser like that
They still have the license, so at least it’s possible. As the upcoming FRIENDS set shows, 2 years seems to be a reasonal gap for a follow-up set (to assess whether it makes sense financially based on the sales of the first set)
However, it’s extremely weird no rumours have shown up yet and the leakers appear fairly unconvinced. We already have information about sets scheduled for November, and they surely wouldn’t tease a set this far in advance
Where would this fit in schedule-wise? The summer/autumn calendars seem to be quite full as is with the FRIENDS set, Daily Bugle, Frozen Castle, Nintendo D2C, Tumbler, Republic Gunship, AT-AT, Harry Potter D2C, and the rumoured Delorean and Titanic sets
Why tease this merely a day before the FRIENDS set?
Why recreate the teaser for season 4 when a new set would most likely be based on seasons 2 or 3? Just to ride the hype train?
