As far as hoaxes go, its not so far fetched.
The drone DOES exist! Its just that it’s a modified Phantom 4 drone with an interchangable lens system complete with prime lenses. This is a custom build drone by DJI for an enterprise client (something that DJI does often). It won’t be available to the public or sold as the “next Phantom 5”.
The official statement from DJI..
“The Phantom 4 drone with interchangeable lenses sighted in some online publications is not a DJI product for public sale. To clarify, this was a modified Phantom 4 Pro drone designed for an enterprise client to serve specific application needs.”
As the time of this writing, people are waiting for the Phantom 5 and the Mavic Pro 2, whatever form those may take. The Phantom 4 Pro v2 has recently been released with small updates including quieter propellors similar to the Mavic Platinum Edition and OcuSync transmision which connect to DJI Goggles. (The new propellers work on existing Phantom 4 systems).
I don’t have any details about who the client id for this modified P4.
