maybe this post from pistachio on discord answers your question:
so if patreons stop the updates will take even longer. And please keep in mind that additional to the IRL problems the 0.7 update is extreme big.

people have been telling us that we should abandon this project and that we'll never finish anything for as long as I remember. those comments are easy to ignore -- and even important to ignore if you want to keep up your productivity.
Hypothetically, if patreon doesn't cover our expenses, we'll switch back to how things were before the release of 0.1, i.e., get day jobs and work on the project in our free time, but we don't plan on abandoning WaL.

Rose's renpy file has 44,206 words in 2,354 sentences
so, yes I think he's correct in saying that 0.7 is going to be a biggish update
