Preorder started around 27-02-19 17:54 and the first member we can "track" is 4805.
Either there where ~4800 pre pre orders F(x) already gathered upfront, or we relatively securely guess ~3800 currently.

Has anyone checked if 4800 is a lucky number in china I know the 8 is. Only guessing from personal experience though. (Behold, another sushi OT) 2014 i did a take-away-sushi trial phase with a local (chinese native) wholeseller, he started order numbers for all new products at 888.

For F(x) it is still a volume > 2.4 mil.$ before taxes at minimum assumption. Minus guessed taxes ~20% they got more than 1.9mil to work with if everyone keeps the preorder promise.
