Yeah, unfortunately Jeff has apparently made the decision to concentrate his activity in the Facebook group, so there isn't much info on his more recent designs outside that forum. Many of his recent designs also seem to be in concert with Meniscus, and for those he doesn't publish xover details - they only come with the kit.
If (like me) you're not on facebook, you can occasionally find a 'permalink' that allows viewing the details without having a Facebook login, but it's hit-or-miss. The new Helios for example can be found, but not the Jintani or the Revolution Mini / Mini BE.
