You can watch all the conferences online via youtube, ign, twitch, your consoles (if offered), movie theaters (sony) and most major online streaming sites.
Microsoft's conference will be aired on the Spike TV channel and website along with their E3 live access for only Monday.
Any news announced will be posted here by the GF staff team. Look forward to some great news folks!
Not sure how many of these I can watch this year, they seem to be at pretty bad times for us UK folk.
Edit - Never mind. I got my time booked off now for Monday and Tuesday so I can watch all the ones I want and will be sure to post them here as I learn the news.
The ones I intend on watching:
Bethesda
Microsoft
EA
Ubisoft
Sony
