First of all: I will so buy this when it comes out!
Regarding censorship in Germany and L4D. The German version is heavily censored. Dead zombies disappear instantly upon death, no flying limbs, reduced blood, no burning zombies. Hell they even censored the box art!
Since I played the demo before hand I knew I could not buy it through steam or the boxed regular version from an ordinary local retailer. Luckily there's a small shop in my town that always imports me uncut UK/US versions and viola no censorship. I did the same with RO, GTA4 etc. A good alternative would be importing from Austria or the UK, especially since the exchange rate pound to € makes UK games pretty cheap for the €urozone.
As an added Bonus I avoided buying through Steam again because their ridiculous pricing policy of 1$=1€ is/was a smack in the face of every European customer and a huge rip-off!
