ign has a preview of the new dash with videos of espn, zune and Netflix.

i am not impressed with any of the "new" integrations they have done. Everything looks pretty much the same. The only things i see is a new 360 intro and some effects that look like nothing more than a theme for your dash.
The ESPN stuff is extremely generic. IDK if they have a plan for more full length shows or full versions of SC or what, but the stuff on it now is nothing more than the 2 mins videos that we can view on espn.com.....you know, the ones you usually turn off your speakers so you dont have to hear their spam
BTW....can someone tell me what the difference is between zune and video market place? these 2 things seem to have the exact same content
