Every set I see posted I get more excited for this show. It'll be strange hearing Baroness do Rays after The Birthing, but I guess the slow intro wouldn't grab people's attention who don't know them. I love them live, though. High on Fire set looks great for me, seeing as all I own is Death is This Communion, and the other two songs I've heard a few times.
And of course, the Opeth set is great and Opeth is awesome and will slay.
