After several Leaks are now already some crucial facts about a new version of the GoPro Hero Actioncamera known, which is probably only soon officially presented. The GoPro Hero 9 Black seems to have a new color display on the front side in addition to the traditional touch display on the back side as well as a larger sensor. The new version will have a 20 megapixel resolution (the GoPro Hero 8 Black had only 12 megapixels), and will capture 5K video at 30 fps as well as RAW and HDR photos.

The improved Hyper Smooth 3.0 function is designed to stabilize videos even better during movements and will certainly benefit from the higher sensor resolution. The combined Hyper Smooth / Time-lapse recording with TimeWarp version 3.0 is also said to have been improved.
With the new model, GoPro is aiming at the strong competition from DJI&s Osmo Action, which already has a front display that should facilitate the correct framing of selfie recordings, for example for Vlogger. Here our comparison:

As with the pre-model GoPro Hero 8 Black it will be possible to control the camera via voice control, for example to trigger the recording without having to press the corresponding button - practical when there is no hand free.

In addition, the new Hero Black will have a 41% larger battery (1,720 mAh instead of 1,220 mAh) than the Hero 8 Black and will be waterproof to a depth of 10 meters. It is not yet known whether the greater capacity will also result in longer operating time or whether it will be needed for the new sensor and color display. A charger with space for two batteries and a quick charging function will be available as an accessory.
In contrast to the GoPro Hero 8 Black, the new model will also be usable as a webcam or live streaming camera by default - the Hero 8 only recently received this option via subsequent firmware update.

An early presentation of the camera in September or October at the latest seems likely.
