While we heard last summer that the HoloLens 2 would use Qualcomm's XR1 platform, more recent reports suggest Microsoft will use Qualcomm Snapdragon 850 ARM processor. Either should deliver high-performance mixed reality and, quite possibly, a more affordable and power-efficient design than the original. It's also expected to have a wider field of view and sport a lighter body, both of which are important for something you could wear for hours at a time. All told, this might be the headset that helps HoloLens evolve from a niche, industry-focused device into something the general public would be willing to use.
