There are not many people actually going to e3.
I was always curious why it matters at all.
As a consumer you have to wait ages and as a journalist you are there a day earlier or have invites.
It's much cheaper to invite all relevant journalist on a global scale.
But honestly? If I'm able to watch the release show from companies like Ms Sony and co live on YouTube I will do that.
I assume this creates more then enough buzz already.
