I get what they offer me and when they offer it. Nuclear Blast is distributed in the US by Century Media (this is a strange arrangement if you know anything about the companies). They seem to be intentionally delaying the US editions of Nuclear Blast titles - sometimes for very long times ie. Avantasia. Why? I don't know and no one can give me a clear answer.
Sometimes CM brings in an import of a Nuclear Blast title and offers it to us at a not so wonderful price, only to follow it with a much more reasonably priced domestic edition weeks (or months later).
Sometimes the US version is identical to the European edition - sometimes not. Always a lot cheaper.
Sometimes they offer titles in sync with the European street date - more often not.
I should probably make this a stuck thread....
