I'd count Demon Hunter as metal, I used to really like them, but find them a bit dull now though. Haste the Day are pretty good, Burning Bridges has some songs that absolutely slay (Blue 42 and American Love FTW) though their stuff since changing vocalist isn't so great. Oh, speaking of which, if you like old HtD or post-metal, or hell just metal, check out their old singers new band Trenches. Just awesomely heavy and epic stuff.
They posted demos on their Myspace page almost a year ago, and Although that's from Wikipedia and is unsourced. Seems too soon. I'd guess news in March or April then an actual album in May-July.
