Mordekaiser release date

Bois, i been wondering what's the exact date uncle brazil will drop. They removed old god Warwick from the coven skinline that we already have, and put it alone in a skinline separately called old god. I'm guessing the coven skins will release with mord too, like morgana and nilah. But anyone has any clue what day? They said mid to late August and we been waiting.
