According to an anonymous source, Game Informer is reporting that Microsoft is set to announce that they'll be allowing self-publishing on the Xbox One. Yes, another sudden, but not surprising reversal in policy from our next-gen overlords.
Current policy for the Xbox 360 and the announced plan for the Xbox One was that all developers required a publishing partner to be released on the platform. Sony also maintained this policy on the PlayStation 3, but went on stage and announced with PlayStation 4 would be different. Since, many indie developers have come forward to state how backwards Microsoft's policy and certification process is and how they dislike the platform or outright refuse to work with them again.
As such, it's absolutely no surprise that Microsoft would reverse its policy. The question now becomes whether Microsoft is doing it because of the PR backlash it's receiving or whether they truly recognize the value of self-publishing. Sony's array of great self-published games at E3 was dazzling and a huge boon to prospective pre-orderers. While Microsoft's policy reversal is promising, until they actively recruit these developers and announce some games, the move is simply day-to-day marketing.
As always, due to the sources being anonymous and Game Informer's lack of any description for as why the sources are reliable, we're marking this as rumor. Nevertheless, we wouldn't be surprised to hear that's true -- and soon at that.
