Bob McKenzie tweeted a few days ago that the weighting of the draft lottery won't change. The only difference is that whoever wins jumps to #1 overall and everyone who finished behind them in the standings slide a spot.
However, that reduced the probability of the last placed team to get the #1 pick from 48% to 25%. This is because under the old system if anyone who finished 6th last or higher won the lottery, the last placed team got the #1 pick.
