Any idea how long the $799 sale price will last on the Phantom 3 Advanced? Most of the retailers are now $799 too. Anyone think the $799 will stay the permanent price or return to $999? I was originally planning on getting the P3P, now I am torn with the $400 to $450 savings buying the Advanced! I don't have a 4K TV yet and I would need a new computer to edit in 4K....decisions!
