"...while there haven't been any official leaks..." ~nice. Also, all things mentioned here are already present in the 12. No glaring issues. Maybe gets a little warm when record/playback/record/playback over and over again. Swappable batteries solve the battery life issue, they're cheap enough to have 4 or 5 on hand and charged. Wait for the 14 or 15 to update the hypersmooth - but it's already fantastic. If you use a gimbal, there is more than enough stabilization here. And why the push for 5K? The only standardization for it is with Apple. Sony/Samsung/LG displays are all pushing for 8K... so... porque?
so they are not going to address the horrible over heating. as a person who has Hero 7, 3x Hero 9, a Hero 10, hero 12 they are all horrible when it comes to having to format and if they come in direct contact with the sun. I still planning to move everything to Insta 360
