Masterplan for me, closely followed by Nightwish, both of whom are way ahead of the pack. Also looking forward to Blaze (who I've seen many times), Hammerfall (who were deeply average live), Saxon (variable -- hope they have a good night), Dragonforce (the spirit of Spinal Tap lives on), PowerQuest and Mercury Rain. The others, I'll decide on at the time. Based on their support slot at Blaze, I'll be in the bar for Fourway Kill. Didn't like Biomechanical either at Bloodstock or supporting Threshold, so I'll probably give them a miss too...
