I sent an email to NFS enquiring when it will be in stock (with a contract) if I cancel my MPD pre-order.

Jon from NFS replied that if I cancel my MPD order (7th of November) and re-order from NFS, I will not get the device any sooner (probably he said it will take longer) since both NFS and MPD will receive the next batch at the same time and pre-orders have already been prefilled.
