Sony has announced that they want to make digtal game purchases more enticing than retail by making it easier for people to get into digital content, with less wait times and more accessibility:

"We're very bullish on digital. One of the things we noticed through the progression of building the PlayStation 4 and now that we've announced it, is that immediacy is a big problem in this industry. Digital is really harmed by that. The difference between an eight hour download and a 15-minute drive to retail—retail is winning that every time. Physical gaming will proliferate as long as that continues. Solving that with PlayGo, which gives you a chunk of the [currently downloading] game you can start playing while the rest is buffered in the background, is a big win for the digital side of the business. I think digital will grow a lot more rapidly as a result of that particular point.

There's 220 million Americans who game, many of them game on tablets and mobile. When you play a game on tablet or mobile, you may not be playing the deep, rich immersive games you play on console, but you are immediately accessing that content. There's not a lot of lag. So we looked at that. And, as we talked to gamers who were starting to say, 'You know I love console gaming but tablets and mobile are engaging my time, we realized that as an industry we need to solve that. PlayGo was born of that. We said, 'We need to make it easier for people to get into digital content, so that people don't have to wait around.

We need to make things easier for people on an immediacy basis, as an industry. We need to make games more accessible."

Looks like Sony is going in a slightly different direction when it comes to digital game purchases, let's just hope that they actually do make digital purchases take less time to download, be more accessible and not force digital downloads on consumers. Many of us still like to buy, play, trade, and collect retail copies of games.
