Historically it tends to start late May to early June. Generation means very little with this promo given that last year (and others I presume) let you apply the $200 iPod credit towards any iPod in the line up, except for when the released the newest one at the very end of the promo. I got an iPod classic last year, and if I get another MBP this year (wifey wants one now) I will probably get a touch this time around.
