As everyone is pointing out. Since you want to omit Japan sales the comparison needs to be altered.
PS2 non-Japan launched in October 2000. Was selling for 2.5 months.
PS3 non-Japan launched in November 2006. Was selling for 1.5 months.
2.5 months of 2000 close to 1 year? NO.
12 months of 2001 close to 1 year? YES.
1,5 month of 2006 close to 1 year? NO.
12 months of 2007 close to 1 year? YES.
Overall:
2001 PS2 = 2007 PS3 - 1st YEAR.
2002 PS2 = 2008 PS3 - 2nd YEAR.
I look forward to updated numbers soon!! :=))
