According to this Reuters story, Arsenal's to allow players watching games live on its terraces to see instant action replays via PSP.
The football club's commercial director, Adrian Ford, said a Sony-developed app would allow fans to watch live streaming video of a game, along with data and statistics, and give the ability to watch near-instant replays.
The personalised system had been tested and could be rolled within 18 months.
That's not the best bit. Sony's also talking about live, in-game communities.
"This device will brings an extra dimension to the game with information and statistics," said Sony Europe retail boss Eric Siereveld.
"But we think that the next generation of the software that runs it could actually link fans during the game with each other."
Up the reds, etc.
