One thing about the new kinect.... why the hell is the optical sensor all the way to one side? It looks odd as hell and I refuse to believe that whole device is packed with equipment. Make it smaller!
Just add a speaker on the end and it would look like a sideways HAL 9000 ;)
On the other hand the XB1 is so much bigger than the PS4 because they had to go for an esoteric RAM set up that may've been a serious flaw in their console whereas Sony being more straightforward could manage a smaller one, so who knows what's going on with Xbox design at all.
Esoteric RAM setup? They're using completely standard PC RAM. If either of the two has an esoteric RAM setup it would be Sony, since 8 gigs of GDDR5 is completely unprecedented (though really, neither setup is all that esoteric...). Unless you're talking about the embedded memory on the XB1, but that has absolutely nothing to do with the size of the system. It does affect the size of the CPU die, but then Sony went on spent that space on extra GPU units so the two chips are really about the same size.
Given that GDDR5 runs hotter and needs more cooling (which it does), if anything I would have expected Sony to have the bigger box. But that's clearly not the case. Wired did a teardown of an XB1 and there's a lot of just wasted space in there...normally console boxes are pretty packed but there's just empty space in the XB1. It's weird.
