I think the problem is you trying to objectively measure people's excitement and how much they should have been excited. I personally was not surprised by either the Playstation conference or the Xbox conference, yet it seems a fairly large amount of Playstation fans and Xbox fans found their respective conference to be amazing. I also know that people's perception of this conference is going to be pure subjective. Sony showed some stuff. Microsoft showed some stuff. What people like and find amazing is subjective.
Moreover, the fact that Sony's conference focused more on "gamers", which you've agreed to, should be clear indication of why people favored their conference. You wanted an explanation, so below I've listed everything you said about Microsoft's conference along with what I think people probably feel about it on THIS site
- New core IP - Sony showed two new IPs
- Improved Kinect - Fans here have largely not cared for Move or Kinect,
- The actual console - This is true
- New controller - Same for Sony
- Fifa w/ exclusive content - Destiny with exclusive content
- CoD w/ exclusive content - People here dislike CoD, for the most part.
- Forza 5 sequel to the highest average Meta racer ever - Sony showed sequels too; and since when have people been that concerned with Metascore, especially with sim racers (see people's love for Gran Turismo)
- 15 exclusives in the first year - Vague announcement by Microsoft
- NFL partnership, Halo TV show, cool media features - All nongaming features, which most people have never really cared for here.
