I really want a dedicated Plex app on Durango. When I'm home I can access my Plex server from my PS3 or 360, but when I take my console to someone else's house it doesn't work. I'm kind of confident it will happen on Durango seeing how Microsoft wants the Xbox to be the only box you have and that Plex has an app on almost every single platform available.
Also, I'm curious to see who's going to be on stage when they reveal the console and talk about the specs and features. This is the list I can come up with:
Steve Ballmer - HIGHLY unlikely, but if Bill Gates could reveal an Xbox in a leather jacket with The Rock, why not?
Don Mattrick - The likely choice. I like Mattrick, he's a smart dude with REAL game dev experience, but man he's not a good public speaker.
Phil Harrison - Would be absolutely weird to see him at a MS event.
Phil Spencer - I think he'll be the one to talk about first party durange games.
Major Nelson - Unlikely, I think he said on his podcast he's going to be backstage.
Marc Whitten - He's usually been the guy at E3 to talk about new Xbox Live features and I remember him unveiling SmartGlass.
Laura Massey - She's a software engineer so she has probably worked on Durango. Plus after the overreaction online about Sony not having any females on stage, they might pick her.
