Years back when Sony launched the PS3 one executive made the prediction that the PS4 would probably not have a physical drive for disc games like the current PS3. After the massive fail that was the PSP Go and its download only catalog Sony has rightfully rethought the download only market.
Sony's Kaz Hirai has stated that the PS4 will have an optical drive and support physical media. He told MCV, "We do business in parts of the world where network infrastructure isn't as robust as one would hope." Hirai continued saying, "There's always going to be requirement for a business of our size and scope to have a physical medium. To think everything will be downloaded in two years, three years or even ten years from now is taking it a little bit to the extreme."
The PS4 isn't expected until 2016 and a lot can change in that time. Last year nearly half of all video games sold were download titles. The download market is growing, but many gamers will still want support for physical media. I know I am glad that the future console won't be download only.
