PS was 11 years (1994-2005). Largely new titles were only really pushed in Japan beyond 2001, but the system was still supported in the states and used PSX games could still be found in stores up until 2005.
PS2 has been 7 years (2000-2007) but Sony allegedly plans on it being 13 years (2000-2013).
PS3 hasn't even been one year but Sony plans on it being 10 years (2006-2016).
Dreamcast has been going for nine years (1998-2007) and has not been doing any stronger than the PS did in its twilight years (2001-2007) with maybe 3-5 unique games released for it each year in Japan. It in every regard has done worse than the PS did considering it hasn't even had a presence in the states in its twilight years.
