Kinect (especially the X-Bone version) is more than just a webcam. I could easily see it contributing $100 or more to the cost.PS4 is $100 cheaper than the Xbox One.
Adding the webcam to the overall cost (+$60), the PS4 is still $40 cheaper than the Xbone.
PSN+ gives you free games every month that you keep and adds online multiplayer this generation for $50. Xbone charges you $60 for Gold and the free games are only for 360.
MS may charge $60 for 1 year of gold, but it is trivially easy to find it cheaper. Getting it $40 or below may have become difficult in the past year, but it still doesn't take much of a search to find it below $50. The only time I have paid $60 for gold is when it was bundled with a chat pad and headset. Remains to be seen if PSN will also be commonly discounted (most likely yes), and what the relative pricing is after discounts.
Moreover, PSN is the only one of the two giving you games you already bought/own digitally on one Playstation device for free on other Playstation devices.
Now we are getting into the real cost differentiators. Although there are hints that X-Bone might play some Windows 8.1 Metro games?
THIS I would say is the most important difference. Especially now that they got rid of family packs if you were using one for streaming to each TV.Plus, a LOT of people buy Xbox Live Gold just to be able to use Netflix with their Xbone. PS4 does not have that requirement. You get to use Netflix without a PSN subscription of any kind.
That's right. To have the option to watch Netflix on Xbox 360 (and Xbone), you pay. To do the same on PS4, you need pay nothing extra per month/year.
The Xbone's only actual advantages are it offers TV features that no one outside the US can enjoy for probably the first year and webcam/Kinect features that failed to make any impact last gen.
Ironically, the 360 is far better in terms of "TV features" than the X-Bone because it has WMC instead of a idiotic cloning of the failed Google TV. In fact, I would argue that even the PS3 has better "TV features" than the X-Bone because of DLNA + DTCP-IP support.
