Destructoid compares PS3 to Saturn, and not in a good way.

[Mr Khan]

There are quite a few similarities between the Sony of today and the post-Genesis SEGA, in their inability to get Western and Japanese managements to play nice, their financial problems, the way they designed and marketed their consoles

 

Of course, you can't build that directly due to Sony's massive non-gaming interests. Sony could come roaring back as a company even if the PS3 and PSP continue to struggle as they have (though its doubtful. Brand name is becoming less relevant in the realm of consumer electronics, especially in these times)
