886677:There has been confirmation from Jeff Donais that the cards go both ways.
At this point there is no way to tell which region a card comes from. If you have two English cards, one was from the EU, one from the US, you wouldn't be able to tell them different.
An english card issued in Europe will not have the words: "stratch gently with coin" on the scratch off portion of the code card. An english card printed for release here in North America will have that phrase on it.
That is the only way to tell the difference.
