PS2 did somewhere in the region of 8 million last year.
I get what you're saying but I dont think sales of PS2 & PS3 are that connected at all right now, because of their price. They're effectively completely seperate entities. The 2 systems are easily the cheapest and the most expensive consoles. Its like comparing a Neo Geo to a NES.
The current success of the PS2 is due to 2 things. #1: Price. People will happily pick up a PS2 for the office TV room...#2: Chances are everyone in the office has a shelf full of games already and waiting to bring in & play. Its become the ultimate casual video games tool. Much more so than a Wii, because the Wii is more expensive and currently has a tiny, tiny fraction of the catalogue and games in circulation and it will obviously lag in that department for years. You can pick up 100s of PS2 games for nothing. The system can be bought brand new for nothing.
All thats proving quite appealing and the PS2 is looking like becoming the first genuine generation hopping console ever made.
