Instead of releasing the Mi 7, a new rumor states that Xiaomi is reportedly announcing the Mi 8 instead. Alongside the Mi 8, a Mi 8 Anniversary Edition is also going to be unveiled. It will serve as a limited edition handset with possibly better specifications and a unique color scheme to attract a crowd that has a penchant for things labeled with the term ‘limited edition’.

As per Chinese resources, two models of the Mi 8 will be released; a regular one and the Mi 8 Anniversary Edition. The Mi 8 Anniversary Edition would cost more than the Mi 8 because of additional features. According to the rumor, the version could be the first to integrate 3D facial recognition technology. Predictably, the costlier version will have more RAM and internal storage and will be of high-quality materials.
