I´m from austria, and I have similar problems.
Amazon.de does list it but is currently out of stock (altough they charged an insanely €75 for it), as is every other board games retailer I know of. I got the last box and core spell tome 1 from another german retailer though, but it seems the core spell tome 2 didnt even make it to the european market.
In generall, it seems they dont consider europe as a market at all, since I know a lot of people who want to buy this game, and only two (yes I am one of them
got it. My favorite games shop in vienna had exactly two copies to sell....
So I hope they start shipping more games to europe because I´d really like to get the new mages expansion as well as more card tomes.
