If you look at these rumours closely, it's pointless stuff to be concerned about. And it's the nature of the beast also, so to speak. Projects this large have various issues present themselves and can be quite dynamic at times. Plus, the whole MS is behind Sony in software development. Isn't that somewhat obvious to expect? SCE have several more teams on software development than them; the majority of whom have matured throughout the last generation. All launch software, or launch targeted software, runs into various issues. It's part of the difficulty of working within constrained limits.
Nothing to miss. He's wrong about the PS4 for one.
