I feel like that this is something that Dish should be selling (ie, a PVR box), not a game console maker. Don't get me wrong, the tech is really cool, but it is missing new features in terms of gaming. Remember, the Wii offered innovative gaming when it first launched, and therefore managed to take a huge share of the market. The PS3 launched along similar lines, and while I really like the PS3, it did suffer for the first few years. In this case, the PS4 is already offering more to gamers in terms of streaming, cloud services, and social functions. I was really impressed with the ability to let a friend remotely play your game. There are many applications for that sort of functionality, depending on how developers implement it. The Xbox One is not offering many gaming specific features so far. That may just be bad press, but even then, just judging by what they announced, it seems like Microsoft did not add many gaming features. The Wii U and the PS4 are already looking more attractive, by comparison. Moreover, the ridiculous fee for used games is just a dumb idea on top of that.
As far as developer support goes, I'm not really an expert, so I defer to others.
Also, the PS4, and the Xbox One, are both providing their own camera system. Granted, we don't know if they are matched, but I really doubt that they aren't at this point...
