About game development? 0. About software development? A lot, as I have 10+ years experience in it. I also know, that most development companies work with sprints and a sprint normally takes about 2 weeks. It was just a question, nothing more. And btw, "when it's ready" is a customer thing, and not how it works internally. You can't tell your PO or PM: "when it's ready" that simply does not exist.
You are 100% right! But you are talking about internal knowledge
We just simply don't know how they planned to release fix / updates - it will be released, when its ready to be.
Maybe they gathering few things to release, maybe they will do small releases (like 3 hotfixes) - we just simply know nothing.
We can only guess but it will still be a guess.
