In the future game developers won't have to upload media to "game journalists".
The industry will change. Dev Podcasts, Devs interviewing other devs, and devs showing off their own game. Game journalists will be giving comments on media released to the public, and beta's they got lucky enough to get in along with other gamers. With their bit of professional opinions, gamers who didn't have time, or get lucky to get into the beta will be see what the game is about.
The industry will change. Soulja Boy will become the top, and most respected game reviewer in the US. Everyone with a camera and access to the internet will be certified to review and preview games. A lot of developers will learn to only release awesome footage however, and Denis D. will release books on tape that teach devs how.
