number of 1st party studios is not as relevant as the number of core games.
You can have 50 studios,45of them making casual crap =no good.
You can have 10,9 of them making core games=better
I think both will do a great job in the beginning of next gen to attract the core gamer as he is the one who is willing to pay 300 dollar and more(nintendo is right now realising this).MSony know they can't come around with a recycled 2d jump and run and some mini games.
I only hope that kinect2/move2 won't succeed.The success of kinect was the reason for low core game support.
