emmm, OK but Nintendo has already did that on Nintendo Wii U - inde dev can publish their game (after Nintendo's approval) without coping with any big publisher. It is funny how Nintendo is super innovative but often overlook (similar as Opera on the browsers market).
The Wii U didn't innovate on this: Sony has been allowing developers to self publish on the PS3 and PS Vita for some time now[1]. This is just a continuation of that policy into the next generation. Much of the news coming out of E3 for Sony has been "we're not changing our policies, unlike our competitor".
