He stopped mid production of the next update. So odds are it'll be start working again at some point in the next two months and then spend at least another month on the next update. Depending on when he starts up again and how much he had done, I would say somewhere between late July to to October until the next update.I'm not clear on whether dev said it's about another month until a new release or until getting back from break, meaning maybe a few more weeks after that for release?
To be clear from my end, I will wait no matter how long it takes as this is my most favorite game and dev.
