I just read an interview with him yesterday in which he says live videos are boring to him, so I wouldn't hold my breath for another one, especially when Get All You Deserve is somewhat recent. Between that and Drive Home the first three albums are pretty covered, a new live DVD would just be HCE plus some repeated songs from the previous albums and maybe 1 or 2 new ones.
He mentioned Heima (by Sigur Ros) as the sort of video that's interesting to him because it's different, not just footage from a single concert. I would freaking love it if he did something conceptually different in that vein, not necessarily exactly like Heima but with the same scope.
