The all-day festival will take place August 9 at Pizza Hut Park, with more than a dozen bands playing on three stages.
The main stage lineup also includes System of a Down's Serj Tankian, Hellyeah, Korn's Jonathan Davis, Cavalera Conspiracy, Shadows Fall, Apocalyptica, In This Moment and an all-star tribute to late Pantera guitarist Darrell "Dimebag" Abbott.
Second stage acts include Sevendust, Devildriver, Kingdom of Sorrow, Soilent Green, Witchcraft and Goatwhore.
The third stage has been christened the Texas stage as "an homage to the many great metal bands that come from Texas" and features The Sword, Drowning Pool and Rigor Mortis.
Festival co-producer Sharon Osbourne promises making Ozzfest a one-day festival this year doesn't necessarily spell the end of a touring event.
"Ozzy just finished an 11-month world tour, so I think he deserves a summer off," she said. "We're going to be a stadium destination festival for now - we have gone past doing the sheds every summer.
"We've given everyone else the blueprint and we have to keep evolving Ozzfest. This is just the beginning; AEG Live and I have a lot of new ideas for Ozzfest."
Tickets for this year's Ozzfest go on sale May 31. Additional info will be available in the coming weeks at Ozzfest.com.
