Don't know that many albums for 2012, but here's the few that I am aware of:

Sigh - In Somniphobia
Diablo Swing Orchestra - Pandora's Piñata
Wintersun - Time (Cause let's face it, it won't be coming out this year)
Busdriver - Beaus$Eros
Deltron 3030 Event II (Del keeps on saying it will be out by this year's end, but I've seen no marketing for it, and I doubt it's going to be a silent release, so I'll say it's out next year)
Devin Towsend - Z²

I've heard rumors of new Nile, Neurosis, Meshuggah, and Candlemass albums, but I don't have anymore info so I can't say for sure, but the six I listed are ones that are at least on my radar.

Pig Destroyer...Harvey is out and new drummer Jarvis is in. I hope they don't end up sounding too much like Misery Index.

This. Also The Mars Volta, Mouse on Mars, and Crudo (Mike Patton and Dan the Automator). All I know of so far - and none are confirmed.

Guided by Voices has one coming out in January that I'm definitely curious about. Also quite excited for new Outkast

I eagerly await new stuff from Baroness and Gallows. That Saddest Landscape album should be good as always. I would love to hear new music from Genghis Tron, Godspeed! You Black Emperor, F*ck Buttons, and Dillinger Four in the coming year as well, those bands are all due for some new releases.

Rush- Clockwork Angles should be released in 2012. The two singles they have released already have been amazing...

Caravan...


BU2B (Brought Up To Believe)...

As would I! :tramp:

Burial's Kindred E.P.

New Gojira and Swallow The Sun albums due out next year, so that's gonna be pretty sweet

New Black Star will be pretty rad, especially with madlib on the beats.
