As somebody previously said: "ROTFLMAO...god, this is why I love this site...too freaking funny!" Oh... Wrong quote, sorry.
As somebody previously said, the consoles are dropping heavily overall. Look at the drops for the quarter: http://www.vgchartz.com/forum/post.php?id=2172152
The consoles are down 35.2% overall (that's without the handhelds, as DS screws things up). Ps3 is down 32%. It's nothing special for the Ps3, as they're all going to hell (apparently). There's really nothing Sony can do to turn it around, well other than perhaps dropping the price. I do, however, believe that this is a bad time to do that, and that it would have a far larger impact sometime else.
So to answer the OP: Nothing. Sony can't really do anything at the current moment (well, at least as far as I see it).
When I write Fact: in one part of the post, and opinion: (or a similar word), it's not because I can then say "my opinion can't be wrong". It is to inform what part is pure facts, and which part I try to draw a conclusion in.
