The real (possible) news here is the report’s details regarding Heimdall, Loki, Thanos, and the Soul Gem, which is the only Infinity Stone that has yet to be officially revealed in the Marvel Cinematic Universe.
Then, the report states Hulk, Valkyrie, and Thor will spend a large portion of the film searching for the Soul Gem in order to defeat Loki and Hela, after the latter helped the God of Mischief usurp the Throne of Asgard.
The site goes into some more spoiler territory, though, when they report that Thor will actually meet Valkyrie on that same planet instead of the presumed Asgard.
Loki will reportedly give the Soul Gem to Thanos (Josh Brolin) along with the locations of the other Infinity Stones in exchange for his own protection when Thanos launches his invasion of the rest of the universe.
