They released another video:

It is impressive that there is no mouse cursor shadow anymore, the refresh rate seems really great!
There is a lot of confusion about it on the web (I blame Dasung's poor marketing skills, they could learn a thing or two from e.g. Remarkable) but there will be 2 models: one with Pearl and one with Carta screen.
On their website one with Pearl has already sold out! From what I understand Pearl with ship in a month or so and Carta edition within 3 months.
The price difference between two is negligible (100 yuan) and based on big difference between Onyx Max and Max Carta I think it is worth the wait.
The price without taxes is around $720 which is a believe ok (no e-reader functionality though). We'll have to wait for some reviews first, but it is looking very solid!
