On-floor updates
-Nice, but unnecessary.  I mean, it's not like a lot of us will just be sitting here hitting refresh for instant updates.
Videos
Photos
Live audio/video
-You know, unless it's something I'm *really* excited about, I don't tend to watch the videos or view the photos.  And, generally, they suck unless they're videos/photos provided by the company.  In which case, everyone's showing them everywhere.
Game impressions
-I voted for this one.  Ultimately, it's what I care about.
Interviews
-This is my other vote.  No matter what every other site is showing, the interviews offered by each individual site will give different info.
Press conference live blogs
-Again, nice, but most of us aren't going to be here hitting refresh all day long.  Did like the Twitter updates though...
