The listing states the certified device is a tablet, coming with the MRX-W09 and MRX-AL09 model numbers which are presumably the Wi-Fi and LTE variants. Another new bit of info is the support for 40W Huawei SuperCharge just like the Mate 30 series.
According to past rumors, the MatePad Pro will pack a 2560 x 1440 resolution display alongside the Kirin 990 SoC and up to 8GB of RAM.
