It's hard to say when it'll actually be available in retailers. It seems that DJI has already started shipping them out directly from China (at least that's where my preorder came from) to consumers who preordered the units. They officially began shipping 28 Jan 2018 but some people have received them even earlier than that. DJI has not mentioned when retail stores shall receive their shipments and how much of those shipments are designated for preorders only or instore display/pickup. I know that's no real answer but the best information I have. Hope it helps.
