Early to mid September sounds like a good release time.
For several reasons, I think it would be great to get some updates from the community perspective on these things - a "what it means/What to expect" kind of thing - especially if it has any impact on the end user layer or experience. The reason I think it is important is that firstly, it creates a lot of discussion and while sometimes messy, I believe this is vital for "buy-in". Secondly, it allows for users who aren't necessarily following all of this to find the information that concerns them through their network here.
Thanks for all your work and these updates :)
