在3月9日Microsoft正式公布了Xbox 2的一些系统规格。目前Xbox 2系统平台代号为Xenon，Xenon CPU有三个3.0GHz PowerPC核心。每个核心支持单周期最少两个指令，都有64KB L1 cache，32KB储存数据，32KB储存指令。三个核心共享1MB L2 cache。但是当前的Alpha 2开发套件都有两个核心而不是三个。

日前Hexus从MS处获得确认消息，Xbox2的IBM RISC处理器确实有三个物理CPU内核，而且每个内核还支持某种形式的"Hyper Threading"技术，因此实际上有6个虚拟处理器。

他们还了解到，Xbox 2在英国的发布日期是今年10月14日，地点是NEC展览中心。
