The eSRAM is in the main GPU/CPU chip. As for licensing costs probably what they save on removing gpu components probably pays for eSRAM. Of course I don't know that but the Xbox One effectively has a weaker gpu so surely costs less than that of the ps4.
Amazed at those kinect numbers. Only seemed like a small percentage of users had it here in the UK. I've seen them sold as cheap as £7.99 secondhand. No good for me though my living room is too small.
