Congratulations! I'm looking forward to the actual release. It's quite hard and risky however, and if anything, previous failed projects are an indication of how volatile all this is (like hardware partners pulling support in the middle of the development cycle and so on).
It would be great to have a device running Linux with native Wayland, and LTE modem separated from the CPU for better security. I just hope they'll go with i.MX 8M so it will be 64-bit.
How is etnaviv for it though? I also wonder what's the level of OpenGL support in it. I suppose Vulkan support isn't even started?
