We’ve known for awhile that Sony wanted to add a social aspect to the PlayStation 4, and one of those methods is through the Share button on the PlayStation 4 controller. We’ve known that you will be able to livestream through Twitch and Ustream, but sadly Sony has confirmed that you will not be able to upload clips to Youtube, at least for the near future.
The official PlayStation blog says that gamers will only be able to upload gaming clips from their PlayStation directly to Facebook at launch. However, they do leave a bit of hope for other options, possibly including Youtube in the future by saying that “PS4 owners can follow PlayStation.Blog and PlayStation.com for further news on other services to come after launch.”
