I've been keeping on eye on the rumors for the last two months, looking to upgrade from my P3P. It's been very quiet. Some guys on the PhantomPilots forum say that the P4P is still the best consumer drone out there, so DJI doesn't have to rush a new aircraft out.
A Mavic 2 with the 1" sensor would be great!
The Obsidian hasn't been in stock anywhere I've seen except limited quanties direct from DJI.
The regular P4P has been fluctuating in price at BH between normal retail and the lower 1300s, today it's 1,299.99 so why would you spend $200 more just for color? Just my opinion.
I've been waiting to hear qualified rumors like you to make a choice between the newest version and the P4P when the price drops even more. BUT a local photog buddy went large and purchased an Inspire 2 with the X5 so last week he made me a great deal on his P4P with a couple extra batteries, filters and a backpack.
With the lousy weather here, I've only flown twice, but it's a nice upgrade from the P3P. The better camera is surely welcomed, but the bird is much more stable than my old one, even in some wind, hoping to do some long exposures that come out reasonably sharp. The ability to control the aperture is also nice and there are several more intelligent flight modes.
With my luck, now that I have a P4P, DJI will come out with a next version of something pretty soon
