I doubt it will be one of the best ever. Tool will come out with a solid album, but Metallica's will suck almost guaranteed. Weezer...I don't know, I've kind of lost faith after The Green Album and Maladroit. If they can return to their power pop brilliance like The Blue Album, I will be happy; I don't think Rivers can go back to the honest songwriting that spawned the great Pinkerton.
I never liked The Strokes, I'd rather listen to Talking Heads and The Cure then cheap knockoffs.
The Who? Eh, your time has been up for a while. When is the last time that a band came out with a good album twenty years after their heyday? Warren Zevon's last album maybe? Brian Wilson's SMiLE?
SOAD may find out what many bands have found out trying to put out more than one album in a year or short period of time: It is hard to write that many good songs. The beatles could do it, but remember, they didn't tour at all. They also had two of the most prolific songwriters in Lennon/McCartney, then they could throw in some classic Harrison joints.
QOTSA...I don't have much faith. They kicked out basically the whole band, they won't return to the brilliance of Rated R or Songs for the Deaf.
Maybe I'll be wrong, I'm the eternal pessimist.
