Hello!
I think that maybe the reason for that Europe in Concert countdown on JMJ's social media is because of a new realease (audio or video) from that tour.
It's interesting that upcoming dates, Berlin and Versailles (September 11th,12th and 24th), apart of Barcelona and others, were professionally recorded on video... maybe it's to dream a lot, but it's a possibility...
Incredibly, those teasers from EiC Barcelona official video, using for that countdown these days, has a very bad quality, nothing remastered.
Or maybe it's a Chronologie 2 album?, what do you think?.
