You're in the right place here, Drumstix- the PS3 Game Comments section you were trying before is a slightly different set up.
Now, as mentioned you won't be seeing the game in Germany. In fact, you won't even get the demo on the German store (what's the point if the full version won't be available, after all). The only way the full version will be available in germany is the PC version, which doesn't require the USK approval.
Just about every other country with regionalized PSN access does have the demo now. If you really want to check the demo out you will have to set yourself up a new username using a different e-mail on the PS3. The trick here is to use an actual address from that area, which can be easily found by picking a spot at random on a Google Map.
