At this year's CES, it seems that Huawei wanted to transition from ODM to OEM company. They have been known for producing their Android devices and now, it also seems that they are planning to release the dual-boot smartphone that will dual-boot both Windows Phone and Android. It will be available in the second quarter of this year in the US but the carriers and pricing are not confirmed yet.
We don't know if the smartphone dual-boot will be true or not in the future as Google might have some guts to stop this kind of plan of dual-boot from happening and especially when Asus is already planning to release their own tablet device that will dual-boot both Android and Windows.
