I'm not sure if I agree with that assessment. A 4/3 sensor is a huge upgrade from the 1" sensor that I don't think everyone understands or appreciates. Image sensors are also very expensive, and cost goes up exponentially with size. Lenses have to be larger to accommodate the larger image circle, which means more glass and more complicated lens designs. On top of that you are getting a second camera with a 1/2" sensor (larger than the
M2Z main sensor).
I don't think they are going to lose any customers, I suspect the
M3 will be so popular it will be difficult to buy for several months after announcement, especially with current global shortages.
If you think the
M3 is overpriced, you probably aren't it's target market and are likely better served by one of the existing drones (I don't mean that in a negative way at all). For someone looking to get a 4/3 sensor in the air with high framerates, it's a bargain relative to anything else on the market currently. If someone isn't excited by that or doesn't need that, then it probably isn't a worthwhile purchase for their particular usage. The biggest win for the market is probably the
Air 2S that is only $999 (~$500 less than the
M2P at launch). When the
M4 is on the horizon, you will probably see
M3 tech trickle down into the Air lineup - it's never cheap to stay on the cutting edge. Also, as you already mentioned, many will be buying this drone for business where cost is largely irrelevant.
