Good luck! I've been looking for an English edition for some time now. You could get an edition in French or German, from Amazon.fr; Amazon.de; or ebay if you search worldwide, as these seem to be abundant.
That seems like the best bet. You can then print off paste-ups of the cards as they aren't used beyond set-up. But at least then you would have the figures which is the most important aspect of teh expansion.
