Google announced this week that Sony has adopted the Youtube APIs on the Sony PS3.
More and more devices like video cameras or mobile phones have now direct upload features for Youtube, so why not also a gaming console.

The Sony PS3 YouTube integration allows game developers to create games that enable direct upload of in-game video captures to YouTube.
This will allow you to share and show-off your gaming skills on the largest video platform out there.
This YouTube upload functionality can be incorporated not only into new PS3 game titles, but also existing PS3 titles that have the ability to receive network updates.
Sony has already added YouTube functionality to Mainichi Issho, a popular game with PS3 users in Japan.
