out of curiosity, when did those other systems launch?

The XBox 360 launched November 21st 2005, the PS3 launched November 17th 2006, and the Wii launched November 19th 2006 ...

wow, thats kinda impressive then o.o

 

@OP: any chance you can make a chart showing software sales and tie ratio too?
