As of my last update in January 2022, DJI hadn’t released a “DJI Mini 3 Pro.” However, if DJI were to introduce a “Mini 3 Pro” model in their lineup, it could potentially include several upgrades and features compared to its predecessors, the DJI Mini 2 and original Mini. Here’s what we might anticipate:

1. **Improved Camera System**: The Mini 3 Pro feature an upgraded camera system with a higher-resolution sensor, improved low-light performance, and possibly even a larger image sensor for better image quality. Enhanced optical and digital stabilization could also be expected for smoother footage.

2. **Extended Flight Time**: The Mini 3 Pro offer longer flight times compared to its predecessors, achieved through advancements in battery technology or increased efficiency in power management. This would allow users to capture more footage on a single charge.

3. **Enhanced Obstacle Avoidance**: Adding obstacle avoidance sensors to the Mini 3 Pro could greatly improve its safety and ease of use, especially for less experienced pilots. These sensors could help prevent collisions with obstacles during flight, providing greater peace of mind.

4. **Advanced Intelligent Flight Modes**: The Mini 3 Pro could come equipped with new and improved intelligent flight modes for automated flying and creative shot composition. Features like Active Track for subject tracking, Quick Shots for easy cinematic shots, and improved waypoint navigation could be included.

5. **Upgraded Remote Controller**: A more advanced remote controller with additional features, improved ergonomics, and enhanced connectivity could accompany the Mini 3 Pro. This provides users with better control over the drone and a more immersive flying experience.

6. **Enhanced Durability and Build Quality**: The Mini 3 Pro feature improved durability and build quality to withstand harsher environmental conditions and ensure longevity. This could include reinforced materials and better weather sealing.

7. **Advanced Transmission Technology**: DJI could implement advanced transmission technology, such as Sync, in the Mini 3 Pro to provide a more stable and reliable connection between the drone and the remote controller, even in challenging environments with high interference.
