In reply to John.
My colleague Michael explained our goals and the thought process behind the new design in the release post here. As he mentioned, this is very much a work in progress, and we will continue to iterate on the design based on the feedback we receive from all Jetpack users, including you.

However, this also means that some things get worked on first, while others have to wait. The old Stats screen is definitely on our radar, but we haven’t worked on it yet. Keep an eye on our changelog, we’ll mention it there as soon as we make changes to the Stats screen in your dashboard.
