Toby Fox has published his latest newsletter, and it includes an update about "what's next" for Deltarune now that Chapter 5 is available. According to Fox, it should be ready to go by next year:"I believe we will be able to release Chapter 6 in 2027. Barring any major restructuring, the main things that will continue to need development time are the boss of the chapter and polishing cutscenes." Chapter 6 is aiming for a release some time in 2027, and according to the previous update, development on Chapter 7 could be underway before the end of this year. Apart from the development update, Fox's latest newsletter reflects on Chapter 5 with additional information and concept art, and also touches on fan speculation and theories.
