Of the big three these are my scores.
MS 7/10
Sony 7/10
Nintendo 5/10
Keep in mind that I use the whole grading scale so a 5 would be an average not bad not great type of score.
I was expecting the most from Nintendo because with a new console should come the biggest surprises. We didn't get a new Metroid, Zelda, or a new main Mario. It was all spin off Mario and 3rd Party stuff. Most of the 3rd party games are ports, which while good to know are coming aren't exactly going to set the stage on fire. Maybe if I was a Pikmen fan I'd be more excited, but since I'm not Nintendo gets a 5/10.
MS and Sony had the same pluses and minuses. They both showed some killer games, they both showed stuff hardcore gamers don't care about, and they both showed too much 3rd party stuff. Neither announced any truly surprising, but what they showed for games does look very good.
So of the top two of the big three it comes down to personal taste. If you like Sony games you are going to think Sony "won" E3. If you like Xbox games then you are going to argue MS "won" E3. Since I'm a huge Halo fan and Halo 4 looks to be the best in the spectacular Halo series, I'm going to say that Halo won E3.
