Ps1 was produced until 2006 (11+ years). And imho the Ps1 sold less in the same time then the Ps3. It was 27 Mio or 29 after 3 years the PS3 will sit on 31 Million.
The PS2 is on the market 10 years and it just launched in Brasil it will stay on the market a lot longer then the PS1 maybe the Ps3 will last easily until 2016. It wont be the only Sony console but they will produce it.
