Returning bands:
Balance Of Power (would be nice), Nightingale (very underrated), Evergrey (no thanks), Silent Force (would be nice), Threshold (would be frigging awesome), Gamma Ray (hey, you never know!), Pagan's Mind (see Threshold), Mercenary (see Evergrey), Secret Sphere (doubt it, but perhaps a chance to redeem themselves), Vanden Plas (would give my left nut for a longer set)
U.S. debuts:
Freedom Call (would be cool, a butt-ton of requests for them), Firewind (another one with a butt-ton of requests, would be absolutely crescent fresh), Andromeda (another left nut band for me), Freak Kitchen (see Andromeda), Labyrinth (see the last two), Loch Vostok (have yet to hear them), Sieges Even (I don't think that would be counted as a reunion), At Vance (see Freedom Call), Blaze (why is he never considered?), Dragonforce (I don't know how long I could handle them), Iron Fire (would be cool, but I doubt it), Iron Savior (see Firewind), Metalium (left nut again, where's the demand?), Nostradameus (would be cool), Pegazus (see Nostradameus), Royal Hunt (could it finally happen?), Running Wild (see Royal Hunt), Shaaman (I wish!), Thunderstone (see Freedom Call), White Skull (see Iron Fire)
I hope that narrows it down a bit.
Stay metal. Never rust.
