Hmm, this combined with that earlier clip gives me much hope for this album. I really hope there is a display of what they've learned throughout each album on this album-- a combination of the best things from each: the heaviness of WTF, the progressive/thrash-y approach to COE, the experimentation on various songs on the S/T, and the emotional quality of the songs from Nightmare. They are a standout in modern mainstream metal, and as such I really do believe they're going to take some risks and produce something fantastic.
Also, they've been hinting at various things around the internet-- one of these things being a possible concept album. They've wanted to do that for a while, so I'd be thrilled to hear their take on one.
