1. Improved Camera: A DJI Mini 3 would likely feature enhancements to its camera system, possibly with a higher resolution sensor for sharper images and better video quality. Improved low-light performance and additional shooting modes could also be expected.

2. Enhanced Flight Performance: While the DJI Mini 2 already offers impressive flight capabilities, a DJI Mini 3 might feature improvements such as longer battery life for extended flight times, increased maximum flight speed, or enhanced stability and wind resistance.

3. **Obstacle Avoidance**: Adding obstacle avoidance sensors to a potential DJI Mini 3 could significantly enhance its safety and ease of use, especially for novice pilots. These sensors could help prevent collisions with obstacles during flight, improving overall reliability.

4. Intelligent Flight Modes: DJI could introduce new intelligent flight modes or enhance existing ones in a DJI Mini 3. These could include features like ActiveTrack for automated subject tracking, QuickShots for easy creative shots, and more.

5. Compact Design: The compact and lightweight design of the Mini series is one of its key selling points. Any upgrades or additions in a DJI Mini 3 would likely need to be implemented without significantly increasing the size or weight of the drone.

6. Improved Remote Controller: A more advanced remote controller with additional features or improved ergonomics could enhance the overall flying experience with a DJI Mini 3. Improved connectivity and compatibility with mobile devices could also be expected.
