The good news for all LEGO back to the future fans is that the set 10290 DeLorean is rumored to be released this year. The news came from Brick_Clicker on social media abroad, who first published information about the set.

According to Brick_Clicker, this Creator Expert-caliber DeLorean set recreates the well-known legendary car from the Back to the Future trilogy. The set may be released as early as September 2021 and costs around 1300 yuan. The set is positioned at 18+, and the number of particles is not yet known, but from the price point of view, he is 200 yuan cheaper than the recently released 10295 Porsche 911, so the scale can also be referred to.
You may not have noticed that LEGO actually launches a Back to the Future set every once in a while, and it's been eight years now. Although it originated from the LEGO Idea platform (it was still called Cuusoo at that time).

Two more LEGO video game level packs 71201 and 71230 Dimensions were introduced in 2015 and 2016.
This was followed in 2018 by Martin and Dr. Brown's square-headed set, the last set on the subject.
Recently, one of Lego's competitors, Playmobil Mobi World, launched a high-profile "Back to the Future" product, deLorean with sound and photoelectric effects. If Lego also launched the highly playable DeLorean this year, it would certainly be popular with fans.
However, at present, this news is only a rumor, and everything is likely to change until lego is officially confirmed.
