So the day one patch for the ps4 is 300mb vs the 500mb for the x1.
Honestly, I'm kind of surprised both are relatively small. I was expecting sizes closer to 1GB, but maybe that is what neither console has all features supported even in the day one patches, to space out the sheer amount of data needed to be downloaded day one.
The PC to USB download is 901mb, but that's probably a full image, not the update. Oh well, I'll download it and throw it up on skydive. I have a feeling I'll have better luck doing that than I will trying to update on launch day. Thanks Microsoft
