Mi Router 3G fixed the biggest grip I had with the Mi Router 3, which is the lack of gigabit ethernet. Even single stream ac wifi can easily saturate 100mbit ethernet single direction. What interest me more is the SoC MT7621A is the same as in the EdgeRouter-X & Mikrotik RB750Gr3, which will make this (& R3P) a powerful & affordable IPsec VPN server/client with with built-in wifi if IKEv2 VPN + HW IPsec support is added to the firmware (xiaomi or 3rd party).
