Well, it seems the Mini has become extremely popular and one of the best selling DJI drones, despite the big uproar about it not having 4K, raw, etc. Even myself have "roared" for those omissions!
But seemingly, the fact that it's less than 250g don't requiring registration and being free from certain regulations in other countries, have contributed to its big popularity and demand, because many people feel less scared of having a drone that doesn't require registration.
However, apparently it's not possible to "add" 4K just with a firmware update to the current Mini, it'll need better/more powerful hardware to do 4K. So the only way to do it is by releasing a
Mini 2 with upgraded hardware chipset capable of handling 4K.
I suppose DJI has been aware of the strong worldwide desire (not to say pressure) to have a sub 250g Mini capable of 4K video and some more features. Currently there's NO other sub-250g drone in existence capable of true 4K video with also a 3-axis gimbal. And the bunch of cheap -250g drones recently appearing claiming to have a "4K camera".. none of them actually capture true 4K video! Their "4K" means they only take 4K resolution
still photos, NOT video, they only do 1080 video!
Therefore, DJI knows that releasing a new sub-250g Mini with 4K (and maybe RAW and a bit more features) will be a HUGE success and a really big hit! That's why, in my opinion, it seems so important for DJI to release sooner than later an improved
Mini 2 with the so-much-requested features like 4K, RAW, etc. I hope it will have all of them!
