At this point there are many ways to gauge a game, twitch has blown up, live with playstation will give you an accurate assessment of how a game plays on that particular platform. There's shareplay, a great feature where you can sample games from friends who buy many games.
The way I see it, review outlets are becoming less and less important for the gamer as a result. I doubt the average PS gamer will go read the IGN review on COD-AW or Mordor, he'll simply fire up live with playstation, see how it plays, listen to the gamer right there on the app for feedback, he can ask questions and interact as well, from there he will form his opinion.
Just as gaming print media has become obsolete, I envision many sites will shut down in the coming years. Remember when 1up was the hottest thing, that's gone, remember when gametrailers blew up, to be honest, I only remembered gametrailers exist since writing this line, have not been on that site for years. I guess this puts things in perspective, at least for me.
