There will be so much hype and buildup on Simone and Gabby that I wouldn't be surprised to see them be the only two doing AA in prelims to ensure they make the AA final. Money and ratings/endorsements could come into play.
Aly is weak on bars, Maggie was a bit weak on beam here. You could do Maggie VT/UB/FX and Aly VT/BB/FX with Kocian/Kyla as UB/BB and come out just fine. There will be pressure to make sure that Simone/Gabby are in the AA final, it'll be bigger than Nastia and Shawn potentially. I think that strategic team planning could come into the picture.
