August has not exacty been a slow month for DS, so I don't know why you say that.
It has already passed the GBA according to this site (though I thought GBA had just managed 80 million myself)
(Edit: DS shipments are 80.1 million)
Sony has never kept a system alive for 15 years... the PS1 lasted 10 years and a couple of months... the PS2 is 8 years old so far.
