Not that this will happen, but I'd like to see both of them drop out. Xbox 360 is my favourite console this generation (Wii slightly behind), but I just want to see a single format for game consoles. I hate having to decide which particular version of a game to buy, having to cart my system to a friend's place if they have a different console, etc.
That said, if I had to pick one to drop out, it would be Sony. True, Microsoft also lost billions in the last generation, but only in the Xbox division. The company as a whole was extremely profitable, which is not the case for Sony this generation at all.
Also, while the damage is not as severe as once thought, the Playstation brand name has been severely crippled this generation.
Finally, on a more personal level, while I own a PS3, I hope they burn in hell, as neither Microsoft or Nintendo, in their worst hours, ever insulted me and you, the consumers.
