Yes, twice now it's been acknowledged that minor details are still unknown. The ONLY thing I am disagreeing with is you made the claim that
"ALL" the specs other than the models have yet to leak, and I am just saying that is absolutely not true based on what DJI themselves have already confirmed. We have some major, headline specs confirmed by DJI, therefore what you are asserting is not true. That's all I am saying.
You will never get a certain level of granular detail until the official announcement, and you don't find out if it all actually works until reviews come out, but key specs such as sensor size, drone size (we do know how big it is unless you missed the photos of the drone with people in them for scale), flight time, speed, range and other headline features are all known and confirmed by DJI. That's good enough for most people until the official announcement - you can't buy it before then anyway. If someone is in the market, we now have more than enough information to know whether or not it's worth holding off until
MP2 is released, or go with something currently available - that is the point. I think the 1" sensor option surprised a lot of people, and made a lot of people interested who had previously written it off (myself included when all rumors pointed to a tiny 1/1.7" sensor as the sole option). Nobody is out there saying to themselves "I think I'll just buy the Mavic Air now because I don't know the exact specification of Active Track 2" - they are looking at things like sensor size, flight time, range, size, body style, etc. You know it's not going to be worse than the existing MP or Air.
Some of the most important changes are not a case of "how much better is it than the existing MP" but rather one aircraft has it and the other doesn't (APAS, omnidirectional avoidance, 1" sensor, etc.)
As for the 1" camera spec I highly suspect it will be 24mm (FF equivalent) F2.8 like in the
Phantom 4 Pro. The lens would have to be made a lot larger to match the F2.2 (almost a full stop faster) of the much smaller 1/2.3" sensor in the existing Mavic Pro while also covering the image circle of a 1" sensor. Again looking at the Phantom Pro where there is WAY more room to hang a larger camera unit, they still went with F2.8 for the 1" sensor. I can't see them putting a larger unit on the
MP2, and based on the photos it doesn't look like they have. I also suspect they needed every advantage to squeeze a 1" sensor into a lens/gimbal housing that fits on the Mavic, and the only ways to do that are not make the aperture any wider than it already is, or reduce sensor size. You can also bet it will be 4K/60FPS with a 100Mbps bitrate because all current applications (even outside the drone world) of the 1" Sony sensor DJI uses maxes out at 100Mbps at that specification. DJI can't go beyond the limits of physics, so it allows us to make some pretty good predictions.
