Ahh, everyone loves a good rumour. Reddit user, /u/ChevStaham, posted the following on /r/Muse earlier today after tickets for a tour date in Mexico went on sale. The Ticketmaster arena diagram shows a 360-degree stage, similar to the set U2 used during their 360 tour (which, incidentally, Muse supported them on in the USA)
I'm secretly hoping for a stage-sized, fully active drone. Please!
