Hard to say. Afaik most consoles tend to peak in sales in their third or fourth year. Iirc Sony themselves expect(ed) to sell fewer consoles this year than last, but with the stacked year it's having and good position for big holiday numbers this year could top it. Then we've got some major heavy hitters coming next year along with potential permanent price cuts that could move the system into impulse purchase territory and reinvigorate sales all over again. I really don't know where the peak is gonna be.
