Typically we don't provide that kind of information - it usually arrives in a "Hey it's here!" delivery, but with the SP-16, the engineers tried to provide an outline for the updates they had planned for 2017. Unfortunately that proved to be a bit of a detriment, as you are aware from the backlash users provided yesterday on the fact the sampler function was removed from the planned update at the last minute.
I've already asked the product teams to give us an official statement on the release yesterday, hopefully it will include a roadmap for you, but even I'm cautious of them issuing another.
And yes, we saw the Facebook group.
