SuperNote A4 X2 13.3 inch roadmap

What is the status of the A4 X2 13.3-inch development? When should we expect it? As a designer/creator and business owner, an A4-sized device is necessary. Similar 13.3-inch devices on the market, like Lumio and quirklogic papyr are nice digital writing devices. However, we cannot compare them to SuperNote software! I will buy it in a heartbeat when the A4 size is available! What do you think?
