While I like to believe that console sales are the only factor in how well a system does this generation, this is not the case. The winner will be determined by console and software sales. The PS3 is doing great and is set to defeat the 360 early next year in WW sales but the software is still lacking. The Wii is not really a threat because developers still see it as a casual only system minus Sega. So the real battle is between the 360 and PS3. This is the only generation where the consoles aren't the same technology wise. Everyone seems to overlook this. Sure the Wii will most likely be the winner, but the games will almost always look like PS2 games and the majority will be shovelware. Developers who want to jump into technology and develop a huge epic game, will not look to the Wii as their main platform. This will hold true especially as technology continues to advance. As it stands now, 360 is still the leader for attach rate and still has a nice chunck of consoles sold to the consumer.
Sony will have to dethrone 360 in both sales and software before we can call them the winner of this generation. I still believe the Wii is competing with PS2, since they are basically the same technology. When the Wii passes 120 million, then it will have beaten Sony. :)
