Unless some major PS4 exclusives really push me over the edge, I'll be buying an Xbox One at launch, and very happily so. I'm really sick of all the hate out there. Anybody who follows the business side of this industry understands that the used games market is a legitimate concern for manufacturers, publishers, and developers alike. Creating an always-online (or semi always-online) console allows PUBLISHERS to address this problem on a case-by-case basis, while improving the consumer-end of the experience (for those with constant connections, a significant market that will grow exponentially in the Xbone lifespan) by giving us already-installed, sharable games that interact seamlessly with our Television programs and internet apps 'n whooseits.
In this way, the Xbox One is the only of the next-gen systems that REALLY feels next gen to me. Microsoft has always gone for the online market, and so far, they've always had the best product for that. Combined with a mandatory Kinect that actually WORKS, and I'm pretty pumped!
The PS4 looks like a good console, and if I already had a Vita and not a 3DS I would totally get it. But the Xbox One is really pretty impressive, and all of the fuss about gamers somehow getting the shaft, or losing their ownership rights, is kind of silly. I've been using Steam for years. Letting publishers go right to the consumer is AMAZING. I just got Saints Row 3 for $10! And all ten of those dollars will go right to the videogame industry. What we are going to see is that very likely, games on the Xbox One will end up costing less. The used game market is MASSIVE, and everybody knows that. Family sharing is super generous, and I don't have to bring anything at all if I want to go play at a friends house.
In conclusion, or TLDR;
Xbox One = Likely really good! Gonna get it!
Kinect = Actually works and isn't an accessory, so actual next gen games!
Used Games = NOT GOING AWAY! More competitive prices for NEW games!
Ownership rights = How many of you actually read your Steam agreements?
PS4 = Also cool! Don't want to get a vita, though! And ugly UI.
Indies = :'( but that's kinda why I have a PC
