I agree that the marketing of titles is key, but I can't agree that there's no evidence that the industry is shifting over to a predominantly digital download method of distribution. Every console manufacturer has made huge moves over the past generation to facilitate it. In the PC space you've got Steam, of course, and EA trying to get a piece of the pie with Origin, plus at least a dozen other download services, not to mention the mobile space. Then you've got the emergence of streaming services, which I guarantee are going to become more and more relevant. And the new indie console, Ouya, is going to be totally download-based. Even the biggest brick-and-mortar retailer, Gamestop, has made moves to provide digital downloads. Like it or not (and I don't, personally) we are in the last few years of physical game releases. Personally I like having a bunch of shelves brimming with games. I like to just look at them like little works of art sometimes. But most people don't want to lug that stuff around anymore. The only exceptions eventually will be the occasional collectors' editions, and the efforts of indie developers like the ones who have continued to support the older consoles long after their own manufacturers have moved on.
