The approach to PS4 we're internally working on is, I hope to see somewhere in-between the current model that we have on PS3 and the PS Mobile totally software-driven model. We could continue and go and expand the PS Mobile approach, but the beauty of developing games on console is we allow the developers to go really deep into the hardware, and to unlock the potential. And so in order for us to do that, the developer has to have the dev kit to work on. So at least initially, we have to provide the dev kit to make games on PS4.
