When is the STEMS update coming out

I don't think that I'm the only one with this question now, when is STEMS getting added to Rekordbox? I have learned everything about mixing so far on Rekordbox, but Serato has had this feature for months and it's really making me consider switching what I use for my software. I love Rekordbox and all the features it currently has, but it's time to finally give us STEMS. We've been patient, but how long do we have to wait?
