Gus looks to be coming in ok, but has a water issue. This seems to be a recurring theme with him, so maybe he loads his diet with sodium right up to the show, and then pulls it while dropping water. This makes sense if he is able to retain fullness while doing this.
His gut looks ok, better than when at it's worst, but likely not as flat as last year. His legs and glutes are holding most of the fat/water left.
My guess is he'll look totally different onstage. Let's wait and see.
