Night 3 will be available around the summer (i think 🤔) at the moment the new Arcade mode update will be released this month, after that they will work on the Christmas update which according from a friend of mine should not take too long to update then it should be available around April then after that there are 3 possibly when the new night 3 will be announced and release there May, June, and July. Also it will depend on how long it will take to create night 3 there is a possibility it will be split up into two parts like night 2 until we know more details we will have to wait and see.
