Gadot’s cameo at the start of the Flash is still there, only her appearance at the end is said to be cut. Since some Wondy fans said Black Adam flopping was proof that Supes/Cavill wasn’t popular, Shazam 2 seemingly set to flop even harder must mean people don’t care about Gadot/WW that much either
In all seriousness after WW1984 reviewed poorly and WW3 got cancelled, I firmly believe Gadot is out after The Flash. I don’t think the general audience will even care that much to be honest, most are likely ready to move on.
