MA2 is threat only to non pro users in a way who don't take advantage of 1" sensor, variable aperture, D-LOG, HLG in 10 bit, there's simply no comparison between 8 and 10 bit among other things, those are main selling points of 
MP2 might even add more functional joystic with like 7 more functions & display + half shutter button , true 20mp sensor...therefore 
AIR2 is nowhere near being competitor to 
MP2 when it doesn't have even half of 
MP2 camera power. There are many other things that are irrelevant to many other users that 
MP2 packs ( omni sensing, quick shots at higher resolution then FHD and so on )
On the flip side IMO 
air2 is best option right now for the average users who don't need full power of 
MP2 at a nice price and I'm definitely getting one for travel and less demanding work that don't need high color grading, mainly because of weight & size that 
MA2 has, in LowePro ProTactic BP AW 450 II  is hard to pack 
mp2 with additional batteries + joystic with camera gear... wheres original Air fits with whole FMC bag and all stuff in it + its much lighter lol.
