It appears The New Microsoft--the one that loves indies and self-publishing--plans on introducing self-publishing not only on Xbox One, but Xbox 360 as well. Previously, Microsoft required all developers to have a publisher, whether a third-party or Microsoft Games Studio, in order to publish content on Xbox Live. That requirement will be lifted when Xbox One launches. However, FarSight Studios is claiming that self-publishing is coming to Xbox 360 as well.
The developer of The Pinball Arcade had their game removed from Xbox Live Arcade once their publisher declared bankruptcy. However, in a newsletter, the developer says that "indie developers can now self-publish on Xbox Live Arcade," and that "this means we can bring The Pinball Arcade back to the 360 ourselves."
In addition, "an Xbox One version" of the game is now possible due to Microsoft's change in policy.
Microsoft, however, isn't confirming or denying the game, telling Polygon: "We have not announced any changes to our publishing policy for Xbox 360. We look forward to sharing more about self-publishing on Xbox One at Gamescom."
Even if Microsoft does introduce self-publishing on Xbox 360, it's unlikely that they will implement the dev kit feature proposed for Xbox One. Still, if this plan comes to fruition, it's yet another sign that Microsoft is changing its policies to be friendlier to both gamers and developers--and that can only be a good thing.
