More good melodic metal bands/albums you might have missed from 2012 so far...Some just released, or about to be, some a bit earlier this year.
LOVE.MIGHT.KILL-2 Big To Fail (excellent follow-up to the also excellent Brace For Impact from last year. Killer hard rock/melodic metal IMO with ex-Firewind/new Helloween drummer)

ECLIPSE-Bleed and Scream (maybe my fave album of 2012 so far. Killer hard rock/melodic metal, their overall heaviest and best disc so far)
http://www.youtube.com/watch?v=LPUzo1fkM38
PERSIAN RISK-Once a King (excellent NWOBHM stuff, melodic metal or classic hard rock, as you wish. Carl Sentance hired a bunch of guys to reform Persian Risk after the original guys bailed out, and he did a killer job. One of my faves albums lately)

CORRODED-State of Disgrace (modern metal from Sweden. One of the only bands in that style I enjoy)
http://www.youtube.com/watch?v=c0BgM5r9LNw&feature=relmfu
REDLINE-Vice (one of my fave albums lately with the Persian Risk one. They got a new singer since 2007's Ignition, re-recorded most of the tracks, added a few new ones, and this gives a killer classic metal album IMO)

THE MYSTERY-Apocalypse 666 (very good melodic power metal with female vox that has balls)
http://www.youtube.com/watch?v=QtsG6mmYvbQ&feature=relmfu
PHANTOM-X - The Opera of the Phantom (good US true metal, singer reminds me of Jon Oliva with his tone)
http://www.youtube.com/watch?v=Mv0afVeTUko
SISTER SIN-Now and Forever (might be my fave by them so far)
http://www.youtube.com/watch?v=ayGmQVSwzKA
STEEL ENGRAVED-On High Wings We Fly (good melodic power metal)
http://www.youtube.com/watch?v=i9Uue3y3Hhc
IMPERA-Legacy of Life (the last album where I heard Alfonzetti's vocals was on 2004's Damned Nation-Sign Of Madness. This new album is cool)
