From GI.Biz: “E3 used to be a retail show. In fact, it still is.
This year continued to be about pre-orders and marketing. It was still about where to buy and how to buy. It still featured publishers and developers partnering with major stores. It was still about the games that consumers will be buying over the next 12 months.”
