Given the November mp update, the CTs aren’t going to get their hands on mp until q1 (which could be either Jan-Mar or Apr-Jun depending on how they view it), so I’d be very surprised if everyone else got it before 1-3 months after that.
We also can be reasonably sure that the next update will be 0.8.5, not 0.9 and I’d think that there’d be a 0.8.6 and potentially a 0.8.7 as well before 0.9.
