Actually, the overseas release is earlier because the overseas distributors have a 30 day window or contract for non-compete against the US distributors
30 days to get there on the boat and 30 days to sell them all before they are released here
on top of that, the overseas market has a new release very 30 days where here its roughly every 90 days
Normally, the overseas equipment is slightly different than ours
in the case of the Mission unknown, they are all the same
