GL.iNet Mudi 7 specs are out and it's now available for pre-order ($319, down from a $399 price target for general release), to ship in April.

noteworthy details:
* 5G and 4G, 6x internal and optional 2x external antennas
* dual SIM support
* tri-band WiFi 7, 1x 2.5GbE port
* 600Mbps Wireguard and 700Mbps OpenVPN
* USB type-C tethering and OTG
* quad-core Qualcomm CPU
* 2GB RAM and 8GB eMMC
* up to 13.5h battery life and USB-PD fast charge
given that it's a Qualcomm CPU I would not expect mainline OpenWrt support any time real soon, but it will be running GL.iNet's build of OpenWrt + their software, and should have access to most packages available on vanilla OpenWrt.
based on my experiences with #GLiNet I would wait for the firmware to stabilize before buying this, with the expectation that increasing competition in the travel router space will push that $399 price target down over time.
