several AC/DC sites, including acdc-rock.com, are mentioning Metallica in their AC/DC tourdates.
The show mentioned is the "Rock Am Ring" festival in Germany. Here Metallica is suposed to play with AC/DC and Bon Jovi among others. This festival will be between 29th of May and 3rd of June but note that the gig is unconfirmed, even by AC/DC.
So, the big question is, is this just another rumor, or can there be for real? My answer is yes it can be. Metallica is probably recording at this time, or have just finished their next album. We all know that they have been doing summer festivals many times as "Some days out of the studio". AC/DC is also on the same management as Metallica and these bands have been doing shows like this together before. Having said this, it is stil a rumor, so I don't belive it before it is confirmed.
