It's obviously just speculation on my part but I think the fact that it's an
air2S and not an
air3 would make it more in line with the mP to mPP or
m2P/
m2Z analogy than mini to
mini2 or Air to
Air2 as far as batteries are concerned and the video, by eyeball at least, seems to corroborate that line of thought. They may have done something different with the propellers, either length or geometry, to get the rumored additional flight time so they MAY not be interchangeable but again this seems to be an incremental improvement not a generational advance so it's possible that they too would be backward( more sideward) compatible. I can't say that they necessarily stuffed a lot more physically in to the
Mini2 than the Mavic Mini but you got occusync 2 for added range and connection strength vs wifi, updated to usb c all around, a 4k camera as opposed to 2.7k, changed the motors if I'm not mistaken to accommodate the different battery chemistry/ capabilites( hence the inability to interchange props) and offer higher speed as well as more camera features. This, if the rumors are true, is mostly just the added upward facing obstacle avoidance and bigger camera sensor if you're in the US. They could have come out at the same time like with the
Mavic 2 and offered the
Air2 for $799us and the
Air2s for say 899 or maybe even 999 and no one would have blinked because of the feature differences but now its a year later and they've only slightly changed the name and offered minor, but I'm sure highly requested and coveted, improvements. The rest of the world finally getting ads-b that never materialized, to the best of my knowledge at least, on the
Air2 would be a potentially huge improvement for them.
