You mean how long it will take to make or how much content will be added?
For the first, I can't really say a set date for when it will be released, but expect it to take around 3 months, as this is how long it usually takes me to push out a new version.
As for the second, I can't disclose that publicly yet, but I have made a post on patreon where you can check some of the new content.
Hope one of these was what you ment by your question!
