Engadget has an image
of what might an ESPN branded Xbox 360
. It's a solid red console with the large ESPN logo on the side. I'm not one of those that like branding on a console but you might like the look.
For me, out of all the updates that got put out such as Twitter or Facebook and items like that, I've used ESPN integration the most. I love being able to go to the various college football games and jump to the important points in the game on the timeline. It's really slick and it's by far the one feature that I and a lot of my friends use the most on the console, not including the online gaming of course.
