However, the ARM versions of the OS (which may number as many as six) won't include any sort of instruction emulation, James saying "Our competitors will not be running legacy applications. Not now. Not ever." That's something that Intel CEO Paul Otellini hinted at back at CES, which means Office running on ARM must have been a re-write -- or at least a re-compile. That's bad news for anyone hoping they'd be able to install Command & Conquer Collector's Edition on the Tegra-powered Windows 8 tablet of their dreams. James additionally indicated there will be four separate Windows 8 ARM SoCs, meaning someone has joined NVIDIA, Qualcomm, and TI since the CES unveil. Intrigue!
