I aggree with HappySqurriel. The numbers right now don't say anything. Wait at least one month, perhaps two, only then you will be able to see in which direction the PS-3 sells go (probably to a lower level than the Xbox 360 due to the price difference).
And the low german software sells are hardly a surprise. The PS-3 is at the moment the cheapest BluRay player, that you will find in german shops. Most shops normaly sell BluRay for more than 1000 Euro. At the moment there are few things that speak for the PS-3 as a gaming plattform, but the BluRay maket will stay rather limited. The market in germany is very price sensititve and a DVD for 8 Euro, compared to a BluRay for 25-30 Euro is a rather clear picture..Compared to the US the german video market was always weak.
