Does Microsoft's HoloLens 2 run original HoloLens apps?

Does HoloLens 2 run apps built for HoloLens 1?

Microsoft tells us that most apps built for the HoloLens 1 should work on the HoloLens 2, but developers will need to update their old HoloLens 1 apps to support any new features and capabilities exclusive to HoloLens 2. For example, HoloLens 1 apps will not be able to take advantage of advanced hand tracking unless the developer adds that support, meaning the user would have to revert to using air tap to interact.

Of course, it will depend on the app. Some HoloLens 1 apps might not work on HoloLens 2, but Microsoft predicts most of them will. Since HoloLens 2 is powered by an ARM processor, many of the HoloLens 1 apps will have to be emulated as HoloLens 1 is an x86 platform with 32-bit apps. Developers will be able to update their apps to ARM64 if they wish.

When does HoloLens 2 come out?

Microsoft has said that the HoloLens 2 will begin shipping to business customers later this year. Consumers will not be able to buy HoloLens 2 at first, but the company hasn't ruled out the ability for consumers to buy their own HoloLens 2 in the future.

This is because most HoloLens customers are businesses, and there isn't much of a consumer play for the HoloLens 2 just yet. Plus, since it costs $3,500, most consumers aren't going to be putting down that kind of money on their own.
