It looks like Millionaire will be supporting dEUS during the upcoming French tour. At least three venues have listed Millionaire as a support act for dEUS. In an interview on the website of Rock Werchter Aldo already mentioned the possibility of Millionaire touring France with dEUS.
Since Millionaire is touring on it's own in The Netherlands at the end of october, there will probably other acts supporting the other dates.
