That's what it looks like to me. Johannes of Lesen.net uncovered a job posting for Amazon's Munich operation. The "Head of Content acquisition Kindle DE" is wanted because:
Amazon is looking for an experienced professional to lead our Kindle efforts with German book publishers and other providers supplying content for Kindle, Amazon's portable reader. This individual will be responsible for building and managing a vendor management team that will work with our book publishing partners to increase the number of titles available on Kindle.
Yeah, I'd say that they're going to open a Kindle Store in Germany.
