The TGS starts at 5am GMT on the 16th or midnight on the 15th in New York and 9pm in LA. Ill be setting my alarm a little early for this one hoping to see some new news and info from GT5. Watch this space.
This is the only link I have for a live stream so far but if i find more I will post it as I find it.
http://tgs.playstation.jp/ (this link now works, i will blog if I hear anything new)
I’m guessing the site is overloaded and i can’t get a connection but I did find the EA stream from TGS here it is.
