Let's face it, unless you are using your drone to make a living, it's just a very enjoyable hobby. As a very serious amateur photographer (which is what I consider myself, even though I have been published and sold many of my works), I have NEVER waited for the "next best" camera to evolve. Had I done that, I would have never experienced some of the best (and worst) Nikon cameras, both film and digital. Hobbies are rarely a money maker, so just enjoy what you have or buy what you want until something better comes along. And when it does, sell what you have and buy it! So you lose a few hundred bucks, but it's pocket-change compared to the enjoyment you may have missed out on!
I heard about the
Mavic 3 rumors and bought a
Mavic 2 Pro anyway, my first drone and love the heck out of it! Shoulda, woulda, coulda is NOT in my vocabulary!
