People have been asking for this for six years. Sony has never said anything more than what is in the knowledge base. Whatever the reason is, Sony prefers not to discuss it. It doesn't really matter what the reason is. Sony owns PSN, and can implement whatever policies that it chooses. Microsoft owns XBox Live, and can implement whatever policies that it chooses. There is no reason why they should be the same. We could speculate, but it is pointless. As far as PSN is concerned, the answer is no. You can't change your online id. End of story. Sony could change its mind, but after six years, it isn't likely.
