The blogger who famously broke the news that Bungie was parting ways from Microsoft has tipped us off to yet another internal MS situation. 8Bit Joystick is reporting that Microsoft is working on two new motherboards for the Xbox 360 to combat the persistent, but apparently dwindling, failure rates of our favorite console. Fifth and sixth generation Xbox 360's are being developed in Redmond codenamed Opus and Valhalla, respectively.
In October 2007, Joystiq reported that the third generation Xbox 360, codename Jasper, was being developed for an August 2008 launch to replace the current Falcon models. The Opus is described as the "zombie Xbox 360 killer," a mishmash of working parts from current red-ringed first generation Xbox 360's (codenamed Xenon) that includes a 90nm GPU and a 65nm CPU fitted onto a Falcon motherboard squeezed into the original Xenon case, which means this console would lack the new HDMI port. This replace-repair scenario was designed to rid Microsoft of the "millions of dead Xenon's" they currently have in stock according to the post by Jake Metcalf at 8Bit Joystick. Due to its refurbished nature, the Opus will never be available at retail and will only be used as replacement units for replacement during RRoD situations.
