Unless you've new information, I would assume that Sailfish is still on its way, but that Davide was a little optimistic in his initial timings. Given how much longer it took for the V23 and then Linux to arrive, and he was specific that work on Sailfish would be worked on only once Android and Linux had been sorted (he explained that the Linux was necessary for Sailfish), my guess would be that we might be due an announcement some time soon. But I haven't written again to inquire and so I've no actual additional info beyond the above supposition and what I wrote earlier.
August is often a quiet month with people away on holidays (not sure whether that has been so true this year). Let's see if there are some more announcements as September gets going.
