Do you think they are done with firmware upgrades for the P3P now that the 4 is out?

Not sure way people keep asking this type of question with FW updates for any of the Phantom 3's. The P4 did not replace the P3's, they are still in production. Personally I like the P3A or P3P over the P4.

The P3 is still a very popular aircraft so I don't think updates are over.

as mentioned above the p4 has not replaced the p3, infact the p3 range (P3S,PS4K,P3A,P3P)is very much DJI'S bread and butter.

I didn't realize they were still producing them.  Thanks, all.
