Tonight Sony Japan is holding their pre-TGS press conference, where they are saying they will bring "...the news you've been waiting for..."
Interestingly, Sony will be providing an English translation stream which you can view here. (Tried to embed into the post but Giant Bomb's message board doesn't seem to like Ustream)
I find this interesting because I seem to recall they didn't do an English stream last year, so by them doing one this year they must want to talk to the whole world in addition to Japan.
The presentation is scheduled to begin at 11pm San Francisco Time (3pm tomorrow Japan time) so adjust time accordingly.
(Hopefully the camera work will be better, then the Gamescom one.)
