honestly i think december 25th is the most likely release date for deltarune chapters 3-5 (if it were to come out this year) because it would line up both lore wise and development wise really well (also it would be a cool christmas gift and it would enforce the omori connections even further)
what if toby fox had an evil twin named tony fox locked in his basement who made a version of Undertale/Deltarune with all the brainrot stuff like "i remember you're genocides", "im wing gaster! the royal scientist!", etc. And all those brainrot posts on r/deltarune were actually tony fox trying to bring his game to the public before toby euthanizes him
