Okay, seems like I don't have to rant about 'vaporware' anymore. As Data Robotics was very quick in replying to my questions whether or when Drobo 2.0 will be available in Germany. The short answer: by the end of September.

Plus bonus points for customer service's reply was not only quick but also personal and elaborate! And they didn't blame something or someone else but simply admit that they run behind schedule because of high demand.

[frustration cooling off] :o)
