There seems to be a lot of contradictory anecdotal evidence floating around. Some schools reportedly are having good years so far, other similar schools reportedly bad years. Some people are saying they are seeing more FGLI admits, some people say they think legacies are doing relatively well. And on and on.
So personally, I would not be ruling out the hypothesis that these colleges will be figuring out ways to legally achieve their diversity goals quite yet. Of course even if so, maybe it will affect the pattern of early versus regular admits, or maybe it will have a shuffling effect among different high schools, or so on. Meaning they could eventually meet their goals but various specific things could change.
But I don’t think at the moment we have anything like the sort of comprehensive information set we would need to really assess what (if anything) has changed.
