<\/figure>\n Xbox fans have been waiting for a glimpse of a new, standalone Game Pass<\/span> streaming device called \u201cKeystone\u201d since it was first teased at E3 2021. Now Microsoft Gaming CEO Phil Spencer may have just given it to them in his latest shelfie<\/span>. It looks like a micro-Xbox Series S.<\/p>\n Microsoft has slowly been bringing Xbox Game Pass to more and more devices<\/span> through cloud streaming. First it was phones. More recently it was certain brands of Smart TVs like Samsung\u2019s. Earlier this year, the company confirmed it was working on a smaller add-on that people could buy to stream games to any display. It\u2019s called Keystone, and so far Microsoft hasn\u2019t shown what it looks like, possibly until today.<\/p>\n \u201cVault Boy left the shelter and stopped by my office to celebrate the #Fallout25 Anniversary,\u201d Spencer tweeted<\/a><\/span> along with a photo of a bunch of Xbox swag on a shelf. \u201cCongratulations to the @Fallout @Bethesda teams on this major milestone for an iconic franchise.\u201d The Microsoft executive has made a habit out of teasing upcoming reveals in the background of his pictures, however, and it didn\u2019t take fans long to spot a strange-looking white device near the top:<\/p>\n
