Well, MS was heavy on Casual Kinect Stuff, Kinect invading on traditional games, and multi-media stuff during their conference and completely neglected to mention Cloud Saving and XBLA Summer titles they have coming.
Nintendo only showed one Wii game and five 3DS games at their conference. When they showed the Wii U, they showcased PC/360/PS3 videos; The tech demos were also a bit underwhelming, they seemed like they could be on the Wii with a peripheral controller. Also, they never actually showed the Wii U itself during the conference leaving many confused.
Sony did lay a bit heavy on 3D and Move stuff this year, but showed the most exclusive core games. The Vita price reveal and demos were actually really cool (the high point of E3).
Overall i would give E3 a B+ on technical Presentation and a C+ on content. If you didn't read any of the spoilers/leaked info prior to the show, it was actually a pretty good E3. Shame many gaming news sites have to kill the magic.
