German World Cup Winners Training Hard For Something That Will Happen in 2010

This looks like viral marketing done right. It's "The Return of the Legends", with great German players of the past "secretly" filmed training hard, preparing for some sort of return. I see 1954 World Cup winner Horst Eckel, 1974 World Cup winning goalkeeper Sepp Maier, and multiple members of the 1990 World Cup winning squad.
