That'll be worth the $500 i'm gonna spend for it. 

sustained strategy of misinformation. Keep it comin' MS, you're digging your own grave. Soon enough no one will even understand what your system's capabilities are anymore.

Based on those photos, the RAM is soldered onto the motherboard (as expected for a console). A RAM upgrade would require higher density memory chips to be used during assembly. 12 GB would be an odd configuration, but 16 GB would be overkill / too expensive.

Although it is possible to do it, I don't think it would be worthwhile.

As someone already mentioned, they would be better off looking at reducing the footprint of the OS. If they can get it down to 1 GB like Sony, they would have essentially leveled the playing field.

As a wild guess, I would assume that they would want to reserve the extra memory for Kinect functionality (to store precomputed values for it to compare against, instead of loading the CPU). A possible solution to this would be to have 2 development modes - one for Kinect and one for non-Kinect. Again, this is a wild speculation, but either way I think the better solution is to spend more engineering to free up existing RAM as opposed to spending more money on each console.

Although if you start to think 10 years ahead, 12 GB of RAM may not be such a bad idea.

The specs are confirmed by MS... only the GPU/CPU clock not.

If that matters too the CPU clock is not confirmed to PS4 too... the GPU is 800Mhz BTW.

@DM235

Two development modes would make the use of Kinect for OS Control impossible while playing a game but MS wants that.

I hope you didn't seriously cancel your predorder. This is just a rumor. 

Also to the people that are saying increasing clocks wouldn't drive up cost, it would. They would have lower yields because the higher the clock, the smaller the percentage of cards there are that can operate at it. 

Depends.  If the memory is separated into banks, you could have a bank of two 2x1GB memory ICs (4GB), then two 2x2GB memory ICs (8GB). 

I expect the OS control to be mainly voice commands and maybe some hand gestures, so it should be a smaller subset of what it can do for a game like Dance Central.

I can't tell if you're arguing for me or against me, or perhaps both.  I think the fact that you can use an external HDD for storage, beyond the limited capability of the Xbox 360, offers the Xbox One an option for the lack of a removable drive.  No, in an Xbox One I can't remove the internal HDD and replace it with a larger capacity drive.  Instead, I buy an external HDD and attach it to the Xbox One and I'm good to go.

Is the storage capacity of a an internal HDD somehow better than the storage capacity of an external HDD?  If they're both 1TB, and they both hold 1TB, doesn't that mean it'll hold the same amount of content? 

The Zebra pattern as far as i understand it was not to hide curves but to identify the console who the dev kit went too. It's like a barcode scanner, if a picture of the dev kit appeared on line you would know which company it came from. Even the Camera had a zebra pattern on it.

As far as the rumour, if they are *only* asking at this point, they would need to get answers back then implement, check for heat issues, testing, electronicts approval, manufacturing tests etc etc. It would be a nightmare. Also its supposed to go into production in August (if not already), so too close or would be very dangerous indeed.

Will have to wait and see, but i think bogus at this time.
