The US shows might be a good indication if they'll change something.
But they really need to change something for the European tour because last time they changed nothing because they were too lazy to rehearse. This time they have way more time, and even they know they can't play the same shit again. They always changed stuff in Europe, even if it wasn't always massive changes.
I'm not expecting a massive change but exchanging a few songs would totally do it, add something new from Hunting Party, bring some older song back would be enough.
