I hope a slightly bigger battery isn't the only improvement.
The Neo 1 has a number of critical problems including poor wind resistance, short range WiFi connectivity, no RTH if using a WiFi leading to loss when in a location that can't be reached if the Neo goes out of WiFi range and generally poor video/still quality on a 4K camera.
It would also be nice if the Goggles N3 were upgraded to support at least the Flip but also the Mini 4 Pro or the upcoming Mini 5 Pro as right now, the ONLY DJI drone it can control is the Neo 1 and the much more expensive and heavier than 250g Avata.
