The stories about the new Phantom have been circulating on the Internet for some time now, but the new teaser from DJI has given us something to think about. As usual the DJI's dramatic video looks like they will change the world, but if the gossip's right they may just disrupt the drone market yet again. Whether it's the completely new Phantom 4 or just an upgrade we could expect anything from the collision avoidance to the improved shell design. Hopefully the announcement on the 1st of March will clear things up and stop us guessing. What changes/improvements would be most preferable?
