Well here's a suprise.  Been waiting for my expansion kit for months from local UK suppliers (tried two on preorder).  DJI have been sending very few quantities of stock over so I've been told.  

Anyway, bit the bullet and ordered direct from DJI and it's already been shipped.  I've usually found DJI store to be slow, but amazingly shipped within 24 hours of payment.

Your mileage may vary...
