UPDATE - 7/2@10:43AM: Alex Lifeson himself also confirmed that the set was in the works at the tail-end of his recent Eddie Trunk interview.
Over the past several years, Rush has released 40th anniversary editions of several of their classic albums, including 2112, A Farewell to Kings, Hemispheres, and Permanent Waves, so it had been expected that they'd give Moving Pictures - which celebrated its 40th anniversary in February, 2021 - a similar treatment as well. But after the 40th anniversary of the album's release came and went without any news of an anniversary box set, it led many fans to speculate (including me) whether there would even be a 40th anniversary release this time, or if perhaps it would just be delayed until later in the year. According to some fans (thanks Fletch G, Brian, Stevie D and others) who attended a VIP meet-n-greet event for Hugh Syme's new art exhibit this past Friday evening at Austin's Ao5 Gallery, it turns out that the latter is the case. Rush's longtime album artist spoke with fans and confirmed that there would be a Moving Pictures 40th anniversary box set coming soon and that he had submitted the final artwork for the set just last week. So it's probably a safe bet to assume that the set will be released sometime closer to the holiday season - likely around November. More news as we learn it!
