The new chapter will have a characters release split into two different periods. The Killer will be released with v5.2.0, while the Survivor, who is currently an original character, will be released later, with v5.3.0.
This could mean, for example, that they managed to get the deal to have only Candyman in the game, and not even a survivor, and therefore that the survivor will be original, but with a release detached from the DLC that contains Candyman for licensing reasons.
