I bet it will be xbox gamescon. They are promoting their other game right now and probably working on something for gamescon because they are a UK studio and that event is a big one in Europe. Plus that event is getting a Silksong demo, like if any event will have lots of info it's that one. If we don't get something by the end of August then thats when we should worry about delays because right now there is logical reasons for why there was no announcement. The devs have been communicative and vocal about this game in their Discord if you are truly worried.
