It would seem the 2chan rumor reported mid-April tastes pretty good even with that grain of salt. The information from the rumor that has checked out thus far is 1. There is a Golden Wizard 2. many people will become Wizards. There are three other elements from the rumor that appear to be in question. Based upon what Sora said in episode 35 of Kamen Rider Wizard about facing Haruto again AFTER he had obtained the Philosopher’s Stone, it seems that the rumor of Phantoms becoming Wizards with the Philosopher’s Stone may be true. The movie ring for Haruto may or may not give him a new form, only time will tell. The fifth and final rumor from 2chan is that the movie ties in to the show. HJU’s DecaEnd has reported that the movie appears to take place

in an parallel world, the Land of Magic, where in Wajima sells Spell Rings from Remnants, demonstrating the rings’ power by transforming into Kamen Rider Mage. The suit for Kamen Rider Mage is the same as for the “army of Wizards” standing behind the Golden Wizard in the Toy Catalog as well as those seen attacking someone in some on-set pictures.
