I see this as the beginning of the short tour before europe ... the announcement is about the NO Jazz ...it's a festival that is NOT a bon jovi organisation ...so it is possibly letting them do that date without much production and then it doesn't mean much about their schedule

me I would say they may begin that 'new leg' unofficially announced dates for south africa isreal etc .... we won't have much more to wait to know , they have to hurry now ...a festival can be announced last minute as they are not the only one performance but for their own dates on their own tour they NEED to do it in advance

I also think they will NOT work during the 2 months between their last dates in the usa and their first date in zagreb ... they will have a break there too
