Well it was 3 months for the last update, so maybe Christmas?
On a serious note, updates are rare, with few and far between content releases.
If you don’t like this practise we need to work together as a community to get them to address the situation, however the ADK is free and not even close to their priority. But if they were to release the content to the ADK and let us test things before releasing possibly buggy or broken content, they would get far greater detailed feedback.
