What they're currently working on getting working:

    - RGB control still needs to be added to hhd or a dedicated application.
    - TDP control might work via OpenGamepadUI overlay mode.
    controller support still needs to be added to OpenGamepadUI.
    - fan curves and battery control needs to be optimized.
    - Audio Equalizer might still need some work to improve audio quality.
    - Standby and Sleep needs some work in software and firmware to properly work.

They even noted the gyroscope model as a BOSCH 260, which is already supported.

Most importantly: what about pricing and release date? Well the good news on both is that it's not far away with a Q2 2024 target (April - June), and they say the price is aiming for the lower-end of Steam Deck pricing so it sounds like it's going to be really competitive there.
