With the recent release of the Mavic and continued focus on the tech being used in the P4, what is the future for the P3 line? I currently own a P3 4K (which I love), but ultimately wanted to move on to the Advanced or Pro. Will these be discontinued soon? If so, will the prices continue to drop? While I could certainly buy a P3A right now, I want I have a better idea of what the future holds for these amazing birds. Thoughts? Updates? News?
