The landscape of technology is changing. It may not be drastic, but it is shifting towards new frontiers. Between virtual reality and augmented reality systems, new skills, methods, and practices may need to be adopted to remain prevalent in the coming year. That said, Microsoft is at least doing their part to try to give developers a clue on what they'll need.
Microsoft is preparing to field their innovative device, the HoloLens, sometime in the future and they want to make sure that developers will have the skills they'll need to work with the new technology. To this end, Microsoft released a brief video offering an idea of where to start in building the skills necessary for developmental work with the HoloLens.
From what the video says, it would appear that folks with a background in C# and Unity will at least have a foundation for handling basic work on the HoloLens. It probably wouldn't be a bad idea to have Microsoft Visual Studios experience under your belt as well. With this, developers can start in "basic holograms" and go from there.
There is no official release date on the HoloLens yet, but the developmental kit is expected to ship sometime in the first quarter of 2016. Nonetheless, it's nice of Microsoft to give folks who are interested in advanced notification on prepping for work with the device.
