I'm going with 10 years ( So by 2022 it will be dicountinued ). Sony has an excellent history of keeping their consoles around for atleast 10 Years:
PS1: 1994/1995-2006
PS2: 2000-2012/2013
PSP: 2004/2005- 2014
Could see them possibly fasing out the PS Vita worldwide by 2020 though ( lifespan of 8 years ) due to it's lack of sales though.
