Someone over on resetera calculated that the ps4 attach ratio is about to hit 10! That's crazy considering we still have so many more years of sales this gen. What a vibrant and healthy system Sony have built.

Edit : ps4 sells 853m SW by end of September. We're only a few months away from hitting 1BN folks. Insanity.
