"According to a posting at the official Ozzfest web site, Ozzy Osbourne will be making a "big announcement" this Friday, May 14 via the first OzTV episode of Ozzfest 2004. Although presently unconfirmed, it is believed that the announcement will consist of the official confirmation of BLACK SABBATH as the headliners of this year's festival, which is scheduled to kick off July 10 in Hartford, Connecticut."

Sounds like Sabbath to me. The rumor has been going around so here's hoping.
