the only 2015 metal (or metalcore, in this case) release I've heard so far is the new 36 Crazyfists album, Time and Trauma. it was pretty solid. definitely an improvement over their last two.
update: got the new Moonspell album Extinct, did not disappoint one bit
the best is yet to come, though. I'm looking forward to a lot of releases, including but not limited to: the Sanctitude live album by Katatonia, The Plague Within by Paradise Lost, Cold Inferno by Disarmonia Mundi, Black Bride by Gyze, Skyline Whispers by The Night Flight Orchestra (not metal, but features members of several metal bands), and the as-yet-untitled new albums from The Agony Scene, Anthrax, Blood Stain Child, Fear Factory, The Foreshadowing, Gojira, In the Silence, Katatonia, My Dying Bride, Nails, Obsydians, Soilwork, Swallow the Sun, and Testament that have either been completed or confirmed to be in the works.
there are some others I'm interested in but not necessarily excited about (the new Megadeth comes to mind) and probably some I forgot, but those are the big ones for me this year.
