I think if you're asking the question honestly, you definitely should at least wait. I mean, there's an absolute certainty that it's both going to cost more and be larger than the Mavic Air, so if neither of those things would make you choose the Air over the
Pro 2, then you should definitely wait. DJI has perfected their marketing skills, and like Apple, they know what to add and what to leave off of a particular device to make it both irresistible and disappointing. What I mean by that is that every Apple product has that special something(s) that makes it irresistible, but at the same thing, they leave something very desirable for an upgraded model. In this way, they are masters of maximizing a potential customer's purchasing power and leveraging that insatiable desire to have something better.
DJI too are masters of this. The Air has several special features that make it irresistible: it has a very portable form factor with a higher end camera and the latest artificial intelligence that DJI improves in every generation. However, it also lacks the best transmission technology, doesn't have the highest end camera technology, and has mediocre battery life. Every DJI product has a series of trade-offs, but for me personally, the Air has just the right balance. Is there a part of me that lusts after the upcoming
Pro 2? Sure, but then I know it's going to cost a good deal more and be a fair amount bigger. The extra flying time, better range, and upgraded camera are very irresistible, but the Air has just enough to make me content at this point in time.
Maybe I'll sell the Air and get the
Pro 2, but it won't be that much longer before something even better comes out. Many of us need to learn how to manage expectations and be content with what we decide to purchase. You can easily drive yourself crazy wishing you had bought a better model OR regretting spending as much as you did on a model you should not have gotten based on your purchasing power or other considerations.
My first DJI product was the Phantom 3 Standard, and I bought it refurbished at a good price. And while I certainly longed for better range, obstacle avoidance, and some other missing features, I learned to love that baby and it was a great UAV to learn how to fly on with minimal risk. The Air is a breath of fresh air for me and I am really enjoying it!
