Sony is having a press conference in about 30 minutes. If you want to watch it will be live streamed at their site.
Many people believe they are announcing the new PlayStation and possibly showing off new games and services. Also recently there have been some leaks like their new controller design and possible November release.
Anyway, I'm excited. Hopefully they show The Last Guardian or something from Naughtydog or Square Enix (Final Fantasy Versus XII?).
