In Flames were scheduled to sub-headline the Zippo Encore stage on Sunday, but they were quietly removed from the line-up poster on 26 February. It was later revealed that they had cancelled all of their Summer shows to finish recording their new album. On 22 March the latest announcement was leaked by "Classic Rock Magazine". Shortly after the leak, Defeater, who were scheduled to play on the Pepsi Max Stage Sunday, were confirmed to have pulled out due to their lead singer, Derek Archambault, suffering an injury and having to undergo hip replacement surgery. Danger Danger were originally confirmed, but pulled out on 7 April, claiming that bookings had been erroneously made for various dates. September Mourning were confirmed for the Pepsi Max Stage on the Friday but were removed from the lineup on 2 May (as they wished to focus on getting their sophomore album completed), they were replaced by I Am Fire. Cage the Gods also pulled out on 2 May. King 810 pulled out the day before they were due to play because their lead vocalist and bassist were arrested. Upon a Burning Body were scheduled to appear on the Pepsi Max stage on Saturday, but were forced to pull out because singer Danny Leal was taken seriously ill with an inner ear infection that meant doctors would not clear him to fly to the UK.
