Does anyone know if or when the mavic pro 2 comes out?

Nope, how should we know it? All you could say would be a prophecy. I don't think that we get a MP2 this year.

I'm sure there is one in the works, with more vision/sensor protection on the side/rear (I would like to think/hope),
But they are going to milk the current generation for all it's worth, then when they get down into the inventories, they will be already gearing up for the next Gen.
That's when we will start hearing "the leaks".........

It's still selling far too well to really look at doing the 2nd.  The phantom is to a degree their test platform which would be why new versions keep coming out so often.

Before will come the end of the earth...

Considering that Spark just came out, I would imagine it would be a long time before the Mavic 2 comes out.

u never know with dji's track record they pop new ones out within a year or less
