DJI believe they can get away with being as arrogant as Apple when it comes to over-promising and under-delivering on orders. I've been buying and flying DJI for over three years and run a business from the UK as a UAPQ-s qualified pilot. We have a collection of Phantom 2 and 3 Pro models plus an Inspire and some Osmos from DJI.
I ordered a Mavic bundle on Feb 4th with assurance of 7-10 days' shipping. My order also included an Osmo+ X3 zoom, some Mavic ND filters and an Osmo Z-axis. Unsurprisingly, the Osmo and z-axis arrived last week and the (crappy) chat agent told me that the Mavic was arriving March 6th. Apparently DJI split the order, at their will, and are holding the Mavic until the ND filters are ready. I offered to cancel the ND filters but this seems to difficult for them.
While DJI have the edge on the innovation it's all good, if a reluctant purchase, but the competition is hotting up. If you want to secure your intellectual property, setting your business up in China may be a disadvantage...
