Air 2 Ultra and Light Question

Hello,
I have questions about the Air 2 Ultra.

I have projects with the Xreal Light. Can I install the SDK 2.2 in my project and is it backwards compatible. Or do I have to set up separate projects for the Xreal Light and the Air 2 Ultra

The Air 2 Pro is available in Germany via Amazone. Will the Air 2 Ultra also be available to order via Amazon after it is released?

Hi developer,

SDK 2.2 is compatible with Light, and you can integrate it into your current project.

I’m not very sure about the second question.
