Speaking with sources, it was said that the game is essentially "Horizon Forbidden West but Lego" and that the game will have "realistic graphics" – whatever that means for a LEGO game.
While the exact details of the game are unclear, I got wind of an advertisement trailer for the game which was completed last month, which suggests that an announcement is on its way (although admittingly could be delayed). But combining this information with Kuraksis'
latest tweet, who finds the majority of his information via trademark filings, it suggests that the trademark has recently been registered (brownie points to anyone who finds it), backing up that an announcement could be soon.
