I had written some proper reviews of my favorites, but thanks to hdd failure, I won't be posting them, just something small. In alphabetical order:
Spoiler:Amorphis - Skyforger (Highest Star)
Great vocals and guitar parts like on their previous album. Sounds a bit recycled at times, but that's only a small downside.
Cain's Offering - Gather the Faithful (Dawn of Solace)
Compared to most other power metal albums I heard this year, this actually sounds new. Kotipelto's voice fits CO better than Stratovarius
Collapse - Visions... (Demo EP) (Come to Life)
Death/doom metal with a twist, just listen to Come to Life and you'll know what I mean. Unfortunately I haven't found a single band that sounds like Collapse, I really like the way they have mixed the piano in it.
Dream Theater - Black Clouds and Silver Linings (Wither)
It may not be their best album, but definitely is worth listening. The Count of Tuscany, Wither and A Rite of Passage are all great songs (and the rest aren't bad either) which should justify listing this album.
Sonata Arctica - The Days of Grays (The Last Amazing Grays)
I liked Unia a lot and TDoG is even better. Like with Collapse, I like they piano parts a lot.

Good, but not great:
Buckethead - A Real Diamond in the Rough + Slaughterhouse on the Prairie (A Real Diamond in the Rough)
Dagon - Terraphobic (Full Speed Ahead)
Luna Mortis - The Absence (Reformation)
Scar Symmetry - Dark Matter Dimensions (Noumenon and Phenomenon)
Warmen - Japanese Hospitality (Separate Ways)
Vinnie Moore - To the Core (Into the Sunset)
Disappointing:
Hammerfall - No Sacrifice, No Victory
Megadeth - Endgame
Stratovarius - Polaris (I had WAY too high expectations for this, even if it was a perfect album I wouldn't be satisfied)
