You would think, too, that Gamestop would enter in that limited physical release market too. Those releases seem to be working and a lot of people like the idea of having a previously digital only game in a physical format.
They could do well going with that approach especially if they limit the print runs, don't over saturate the market, and offer limited edition stuff or collectors edition stuff. It would go well with their think geek business that sells geeky tat.
There is definitely still a market for physical games and there may always be, but I think the returns and expectations need to be managed.
