WEX Photographic confirms on their website what I already reported here on NikonRumors: the first Nikon D5 shipments will include free Sony 32GB XQD memory card and reader.
Jessops has a similar note on their D5 listing:
Note that the Nikon D500 listings at WEX Photographic and Jessops do not mention anything about free XQD cards.
The new Sony XQD M-series memory cards are currently shipping in the US.
