Rob, I think we have one other good reason to believe 6-core will be the choice: AMD already makes a good 6-core chip. going to 4 cores plus HyperThreading on this kind of system would actually be a bit of a performance hit given Kinect will require a dedicated thread at all times...and since the GPU maker of choice also already has an x86 6-core that's affordable and an excellent performer, it just wouldn't make sense to go to a 4-core+HT Intel chip.
@Darkstarr:
Please remember that the modding community and second-hand games market, though very devoted, are both very small fractions of the system users at large. Though we "true geeks" will not sit quietly for such egregious anti-legitimate-user methods, it's unlikely that your average gamer is going to give half a rat's ass. For instance, thanks to the Wii, my dad now loves Tiger Woods Golf. It's accessible to him, it's fun, and it's something he can do on a rainy day. The benefits of Kinect will simply add to that.
Most people have their XBoxes and PS3's connected to the internet at all times anyways, and part of the new selling features are a "family friendly" entertainment device that would always be connected. As such, you're unlikely to find a non-techie that's going to give a shit - at least right up until they want to sell a used game, which many people don't do to begin with.
It's part of the benefits that MS can see moving to a more "mainstream" audience instead of just hardcore gamers...not only do you move more systems, you also get a whole lot less whiny people when it comes to rights violations. One only has to look at Sony, which was so successful at selling the PS3 as a "media device" (which it actually excels at) that it was able to utterly castrate homebrew publicly and STILL sell.
We have to remember that we are the minority of the market now. We may be a very vocal minority, but we are the minority. My dad will still play Tiger Woods Golf even it sends pictures of him to the government and tries to RFID-read his credit card, simply because he doesn't know better or care. It's not an inconvenience to him; and until it is, he won't sympathize with a small market share that is already known to be unscrupulous and shady.
