This is a few days old, but I just stumbled across it. Dream Theater's 10th studio album, Black Clouds & Silver Linings, is being released June 23, 2009. I really loved Systematic Chaos (although the title song was my least favorite on the album) and I've get recently gotten back into Train of Thought.
The album only consists of 6 songs, but I suspect it's a good 80 minutes of music:
The album is being released on vinyl as well as a 3-disc Special Edition that will contain extra CDs—one, an instrumental remix of the album and two, a six song cover CD.
