That is correct online Playstationers (not actually a real word), as of today you can now view your trophies online by signing in on Playstation.com using your Playstation Network ID.
The video above gives you a rough guide on where to look for your trophies as well as how they now work and what you can do with them while online. It’s good to see that Sony are constantly adding more functionality to their services, and according to the video this is only the beginning of what they have planned.
