In terms of profit, Sony probably don't care too much if the hardware sales are down as the PS3 is still making a loss. They're pushing the software more in order to increase sales. Worldwide only 11000 behind 360 isn't that bad in terms of sales (although one could argue they're both doing bad due to the current economic climate).
They really need a boost in the US and UK and if the UK is anything to go by, they really need to advertise more. But why would they want to advertise something they lose money on? If anything, they need to advertise their first party software more.
