Here is why i think the X1 will beat the PS4

[ArnoldRimmer]

What exactly would those "exciting technological breakthroughs" be?

Kinect 2 is hardly more than a resolution-improved Kinect 1. This improved resolution etc. will improve accuracy etc., but it won't allow for exciting new features that wouldn't have been possible before. So if someone wasn't convinced by Kinect 1, it's unlikely Kinect 2 will make him very excited

What remains? The new TV-centric features are the only new hardware features coming to my mind. And I just don't see those making too many people excited. First of all, "Live TV" appears to require a seperate TV decoder/receiver device connected to the X1's "HDMI IN" port. I've read that such receivers are indeed quite common in the USA, but not in Europe for example, where almost all recent TVs already have them included. The other problem of course being that at least initially it's just a feature available in the USA. So in the end, these TV-centric features may indeed lead to the Xbox One being very successful in the USA. But since "X1 will beat PS4" can only mean winning worldwide console sales, a feature that's great but only usable for customers in one country is unlikely to make it the most popular console worldwide.

But even among Xbox fans from the US, there just doesn't seem to be that much excitement for these features, at least so far. I've looked at all threads in the "Microsoft discussion" forum that have been created since the Xbox One reveal, and I couldn't find a single, positive thread dedicated to the new TV integration features. Even the Xbox fans from the USA hardly seem to care about that feature. Multiple threads were created where the original poster pointed out various disadvantages of the TV integration features, but that was about it.
There was one "positive" thread about X1 having Blu-Ray, but on the one hand that has not so much to do with TV integration, and on the other hand, that's of course not a real selling point for the X1, as this already was a last-gen feature on the PS.
Another "positive", multimedia-related thread was about X1 being capable of 3D and 4K. That's nice, but again, not an advantage of the rival, the PS4. 3D was once again already used in the last-gen PS3, and 4K is something the PS4 is capable of, too. And apart from the fact that 4K will remain a niche feature for at least a couple of years, neither console will make much use of it anyway.
