Kinect, weak Yen, and I'd also add that the PS4 just may be the more efficient console. Every XBox has been pretty big, with an external power brick, and they've definitely had their battles with overheating. Sony is an electronics company first and foremost, so I think Sony just has the upper hand when it comes to engineering the hardware. Most PlayStation iterations are smaller, quieter, and cooler than their XBox counterparts with internal power supplies. I'd have to imagine this also helps the bottom line due to less materials being needed. With the yield problems XBox One is rumored to be having, they've made another giant console with a ton of cooling (it seems).
It's mostly the bundling of Kinect though.
