Here we go with those trusted sources again. Edge has it on good authority that Microsoft's midlife rejuvenator for the Xbox 360, Project Natal, will cost a cool 149 bucks when purchased as a standalone accessory, or $100 when bundled together with the $199 Xbox 360 Arcade console. That's a mighty steep hill for early adopters to climb, but Microsoft did warn us that Natal will not be an impulse buy . An October 26 date is also proffered for the official launch, but that might shift, leaving us with the same window of expectation as before. Interestingly, the Natal name is expected to definitely change for the final retail product, which we should be learning a lot more about at E3 in a couple of weeks.
