The ones I like the most so far in 2012 are:
SUNSTORM-emotional fire (excellent hard rock/AOR, Joe Lynn Turner still got the pipes at 60)
DEVIL'S TRAIN-s/t (excellent southern-tinged melodic metal with the Mystic Prophecy singer and Jorg Michael on drums)
PRIMAL FEAR-unbreakable (just another excellent traditional heavy/power disc for them)
DYNAZTY-sultans of sins (excellent hard rock/melodic metal)
ACCEPT-stalingrad (not as great as BotN for me, but very good stuff anyway)
AXEL RUDI PELL-circle of the oath (more of the same, but still quality stuff with the killer vox of Johnny Gioeli)
LEGION-nemesis (damn fine traditional HM. These guys are productive, 3 albums in 2 years or so)
KISSIN' DYNAMITE-money, sex & power (they brought black the glam look, but their music is heavy enough hard rocking stuff with lots of hooks)
ASTRAL DOORS-jerusalem (another very solid disc of traditional HM)
My faves of the bunch would be DEVIL'S TRAIN and PRIMAL FEAR.
Others I've been enjoying are:
MAD MAX-another night of passion (fully good hard rocking stuff with no ballads this time)
SHINEDOWN-amaryllis (not as great as Sound Of Madness, but still some very good songs to be found here)
A SOUND OF THUNDER-out of darkness (didn't know them. Very solid melodic metal, with excellent female vocals. This is coming from a guy who is not a major fan of female vox in my metal)
GUN BARREL-brace for impact (one more good power rock'n'roll melodic metal from the Germans, with a new singer that fits the band well)
MOLLO/MARTIN-the third cage (some killer songs, some lesser ones as well though. Martin still in fine vocal form)
ADRENALINE MOB-omerta (well, there is some weak, un-melodic stuff to be found, but I find myself really enjoying at least 4 or 5 songs)
