Probably not very soon, since they first have to release v1.1.0 (Steam version) and start their Kickstarter, and we also have to take into consideration that Ch1 only came out 5 months ago, and when we look at other multichapter games like deltarune we will find that it takes about a year or even more just to release a single new chapter (altough deltarune chapters 3-5 will release at the same time)
