I agree with this assessment but I'm baffled at the idea that they'll find a market out there for a device like this.
Baffled, really? Home consoles today are being used for more hours to watch netflix and the like than they are for gaming. The original Wii sold a bajillion units on braindead hardware by appealing to kids, parents, and grannies with kiddy motion games. More and more people are getting their gaming fix from simpler experiences on much smaller devices. And neither console, despite their GPU improvements, represents the kind of leap over their predecessors as the previous generation did.
I agree with your assessment that Microsoft has foregone the high-end, but I'm baffled why you're baffled :)
Here's the scene I predict all across the US this holiday: 10s of thousands of parents, standing before Xbox One and PS4 displays, realizing that they can get an Xbox One, a game, and an extra controller for the price of the PS4. That mom and dad get all the cool TV/VoD integration when the kids are away, and that little Suzy can play all these neat Kinect games when her older siblings aren't using it. That Billie is always excited about new CoD maps, and that those are coming to XBox One first. Dad's in love with the ESPN and NFL content, and the fantasy sports integration. Mom's in love with the TV content and skype integration.
Do I think there might be a number of 16-30 males jumping ship to PS4 this generation, sure. Do I think that MS will more than make up the difference in appealing to a broader audience, even surer. PS4 is the stronger proposition if all you really care about is gaming, Xbox One has the stronger proposition for everyone else.
I don't know that Xbox will launch at a lower price, but given the difference in hardware choices, that's my prediction. We haven't seen a price disparity between similarly-capable hardware since the Saturn vs. PSOne, which we all know went to the unproven, but less expensive newcomer. I think price will have a lot of sway, especially in this economy. And Flying Spaghetti Monster help Sony if they have yield issues on their massive SoC, or supply chain issues with their unprecedented need for high-capacity GDDR5 chips.
