Wow, seems pretty logical. Hopefully they would do all these three. The festival here changed its date to June 26th-27th so that they don't have to compete with Novarock, Download which were at the same weekend.
Also, let's do no not forget Roskilde in Denmark which is also about at the same time. Anyways, I'm really hoping they would come here at the Provinssirock festival because I live next to it and can pretty much walk there from my home.
