siliconbits writes: Microsoft announced a bombshell earlier today by saying that it became an ARM Licensee, the only software company to do so. This has given rise to speculation that this may mean that it will launch CPUs (or SoC) in a near future.... Xbox 720 on ARM Cortex-A10 maybe? ARM has announced this morning that Microsoft has become the latest technological company to license its ARM architecture, a significant step which could have some deep consequences in the tech ecosystem. Both companies have been working together since 1997 with Windows Mobile and Windows CE being the two platforms that Microsoft uses for ARM. The Microsoft/ARM agreement extends further though because Microsoft now has access to the full portfolio of ARM's instruction set.
