My opinion is that the fanbase & general public are taking the "dont buy the PS3 untill the big games out"-approach. That, and the Wii price is probably a good factor aswell.
More than likely we won't see people buying more PS3's untill the likes of MGS4 makes a dive, and finally gets released.
But I also believe that its due to the hardcore base being split into the 360 supporters and PS3 supporters. If that crowd merged, the sales would be strong.
