Xbox 720: countdown begins to E3 announcement

"As for the specifications of the hardware, game sites are already making educated guesses, based on developer titbits and a bunch of leaked documents apparently revealing a Microsoft Xbox roadmap for the coming year. Tech Radar is not alone in expecting a quad-core Intel processor and 8GB of memory; a huge leap over the Xbox 360 specs
(although developer sources have indicated to The Guardian that we should expect 4GB of memory). An Nvidia graphics chipset is also likely, as is a new generation of the Kinect motion control hardware, which could support up to four players simultaneously.
Now that Microsoft has apparently placed its cards on the table, Sony will doubtless follow. A PlayStation 4 announcement has also been expected for some time and Sony will not want to give Microsoft a head start, as it did with Xbox 360, which arrived a year before PS3. It could be that Sony will line up a rival announcement at E3, making this the most important video game trade show for several years."
