It's been three years since Microsoft first introduced the world to HoloLens, so it shouldn't be surprising to hear that the company is hard at work on the next-generation headset and has been for some time. Codenamed "Sydney," here's everything we know about the unannounced Microsoft "HoloLens 2."

HoloLens 2 hardware

Microsoft has already confirmed that the next HoloLens will have a new, custom Holographic Processing Unit (HPU) that will feature an AI coprocessor to natively and flexibly implement Deep Neural Networks. That means HoloLens 2 will be able to analyze visual data locally, without needing to send any data to the cloud. This should make the HoloLens faster at recognizing objects and environments.

In addition to the new HPU, we hear that the next HoloLens will be powered by an ARM processor and include LTE support for true-mobile holographic computing. Our sources suggest that the next HoloLens will be more mobile than ever, with longer battery life and an always-connected state. It is likely the HoloLens 2 will also include a wider field of view, something the original HoloLens caught a lot of flack for.

HoloLens 2 software

HoloLens 2 will run a version of Windows 10 built on Windows Core OS. This version of Windows 10 is codenamed Oasis, and is a Mixed Reality-specific experience that runs on HoloLens 2 and likely other Mixed Reality devices in the future. HoloLens 2 will also feature CShell, Microsoft's new adaptable UI that works across all device types. I've written about both Windows Core OS and CShell in extensive detail over the last year, so if you're unsure of what these are, make sure you hit the following links:

HoloLens 2 release date

Microsoft is hoping to announce HoloLens 2 within the next year, before the end of 2018, but that date could easily slip back to early 2019. Microsoft was originally going to announce HoloLens 2 a lot earlier, but it decided to wait because there is no immediate competition in the market, and it wanted HoloLens 2 to make a huge splash with new features, experiences, and capabilities.
