Along with Sony's latest 4K OLED TV announcement, we can expect to see the very first 4K video distribution service from them as well. This has been a prominent issue for early adopters who are concerned with how much actual content will take advantage of the 4K resolution.
Think of it as a Netflix for 4K content. This will help sell and promote the 4K market that Sony is trying to create. While this is a dandy idea, take a second and think about your Internet connection. As you can imagine, High Definition that go as high as 4K may not play too nicely with your bandwidth. It is still nonetheless a push from Sony that we will see within the near future. There has yet to be anymore details from Sony but we expect a launch in the US sometime in the summer.
