this, there’s no implication that it’s even scheduled for reset just that they’re working on it and asap usually implies it could be a little while
besides that even if they did change mmr in some form people would still have to play and climb so you’d be waiting a week+ AFTER the changes to see the ladder actually move
they explained how the mmr post SLS1 works in DFS1
they don’t start adding mmr until week 10 generally though
nobody knows if they’d started earlier this season
