Ok, I got some news by GPD. G5A is discontinued but will be manufactured for OEMs. That means there will be other brands who will sell g5A (with a different name I guess), but GPD will stop selling device by themselves with their brand. I don't know why, I am not a commercial, but I guess device is not as profitable as they expected, or they want to put all their effort in new devices, I don't know.
