As it stands, the PlayStation 4 seems to be winning the 'next-gen' and now current-gen console war, with the Xbox One lagging behind. Microsoft obviously wants to change this, something that was pointed out in an interview with The Inner Circle Podcast, with the head of Xbox, Phil Spencer.
Spencer said during the interview: "I'll announce it here: I was told themes and background [pictures] are something that we are working on. And screenshots, I know people beat me up on screenshots". Spencer is aware that Xbox One gamers want to be able to personalize their dashboards, and do things that PC gamers can do easily, such as taking in-game screenshots without having to have the game have a built-in screenshot-taking feature.
He wasn't willing to tell the world when these new themes, backgrounds and screenshot-taking abilities would be appearing, but he did say "people should know that they're in development".
