Apparently, it has been saying for this years ozzfest the confirmed bands are:

Black Sabbath
System of a Down(Reunion Show)
Marilyn Manson
Disturbed
Slayer
Mudvayne
Slipknot

I have been looking all over to see if it really is, I just don't know where, but I'm thinking it is true for ozzy was answering questions and ppl asked about ozzfest lineup and those are supposedly confirmed.

Wtf?????
Thank God I live in Germany
If this really should be true, I hope that SOAD will not just play this one show...

Holy shit! I love all of these bands! Well except Slayer. And I hope SOAD really comes to it. I love them. I saw them in Ozzfest 2006.

I seem to remember them confirming that Ozzy was headling as a solo band this year. I think it'd be cool to have Black Sabbath and Heaven and Hell doing ozzfest. (Manson, too, duh. He always seemed to love doing Ozzfest.)

Holy shit that sounds good. I wonder in what form they'll be doing Holland. Usually it's not OzzFest but a similar festival with a lot of the same bands.. Rock am Ring, Rock in Park, Fields of Rock, etc..

@Ron Zombie. Well slayer is good, like I NEVER cared for them until mayhem fest, but I'm still in that place of I like them, but they seem to be the same to me. Also, if you guys like rob zombie his new album is good, and will be great at mayhem fest this year lol.

apparently Ozzy is doing a solo set...SOAD are DEFFIENTLY not reforming according to Serj(the lead singer - he posted to the press that the band are still on hiatus) and i doubt Manson will be there but we can hope for the best

Well... I have my resources and right now its supposedly on it might might not happen kind of thing so who knows. Like you said, lets hope for the best
