There won't be any live blogs or whatever. Those are pointless with how many live video streams there are going to be. Will I live Tweet my reactions to announcements? Probably. I will at least try to put up a thread with an embedded video stream prior to each show starting.
I'll probably watch a lot of the conferences through GiantBomb.com. They will stream all of the conferences but will be talking over all of them. If there is an important reveal being talked about on stage, I'll have another stream ready so that I can catch the details without people talking over them. This year, I want to enjoy the conferences more as a fan. I haven't really had that in previous years because I pushed myself to get news up as fast as I possibly could for almost no reason. Those single line news posts didn't really offer up much anyway. "Oh, a new Tomb Raider game was announced but this news post has no details, screenshots, or the new trailer? That's cool." Then you had to wait until later for another news post to go up that finally had the new information, trailer, or screenshots in it.
Trust me, there's still going to be a ton of news going up with tons of new trailers. I better go get some sleep while I can.
