I don't know the Rosetta Stone language courses but since they're so renowned they're probably speaking Hoch Deutsch (High German). I probably haven't heard a ton of Hoch Deutsch, but what I have heard didn't sound latinized to me. German in general was less harsh than I expected it to be. I find that it only sounds really harsh if the person speaking does really good rolled r's. If you want to hear harsh German listen to some Rammstein.

Oh yeah and I survived the huge storm that hit us here on Thursday.
