A rumor cannot be used to disprove the validity of another rumor. I understand the desire to think that we are more knowledgeable then we actually are, but all of the rumor sources have been fairly well proven to be untrustworthy, or outright wrong. Anyone claiming otherwise is practicing some serious revisionism. We have hundreds of rumors about the next console, and just by the law of numbers one of them is going to be close to the mark. Why so many rumors. Why the hell not starting a rumor costs so little credibility, and in the off chance they are right their online credibility goes through the fucking roof. Just for taking a educated guess.
This guy is actually pretty clever, because if the memory that Microsoft is using in their new machine is indeed the one he specified. Which is contrary to the other rumors that have tried to stay similar to one another. This guy is going to look like a prophet. Would you like to here my educated guess about the new hardware.
For one I don't think a Kinect will come included with the console, or that there is even going to be a new version available at launch. I suspect that Microsoft will be more then happy to support the original peripheral as a legacy device for their new console. While they intend for the next iteration of the device to come packaged with their new holographic peripheral. Which wont launch until the next console is a couple years old.
Speaking to system memory purely as a matter of deductive logic, and a desire by them to stay on par with Sony. I suspect that Microsoft will have certifiably more under the hood, because of the holographic technology. That tech is going to be resource intensive, and they wont want to place developers in a position where they will have to compromise quality in their games to support the device. In other words Microsoft isn't going to want third parties to cut back on in game assets to put on the light show.
The higher added cost will be more then justified by the expansion of the product line into many more homes, and the peripheral sales they will expect to see later on in the generation. The device isn't explicitly a gaming device after all. It will be a visual surround sound system for the family, and movie studios will probably start to make their movies around incorporating the feature in their moves, and that will mean serious licensing fees for Microsoft.
