From my point of view, if your talking about the amount of games introduced and enhancements to the systems, its definitely Sony who won E3 2009. But if your looking at the technology, then its Microsoft hands down! Microsoft's games were less exclusive and more platformers and not so expressive as Sony's. Also, Sony introduced new features here and there to PSN(PlayStation Network) and to the communication of the PSP and PS3 which are by far very impressive! Also, the new, sleek, light, stylish PSP Go is what stole the show the most!

The presentation of Gran Turismo PSP was also most impressive as it took the PSP's capibilites to the limit even on this small piece of hardware!

Sony was also successful in the games portion of the Playstation 3. Some exclusive games that shocked the audience including me were:

1. Uncharted 2: Among Thieves

2. God of War 3

3. Final Fantasy XIV(Also Final Fantasy 13)

4. MAG(Massive Action Game)

5. Rachet&Clank Future: A Crack in Time

Sony just announced the new motion controller for the PS3 -- the prototype looks like a wand with a color-changing ball on top but it is said that the final product will be changed. Unlike Microsoft's Project Natal, Sony says they've learned "some experiences need buttons," which is why there's still a controller with buttons involved. The system is said to be "sub-millimeter" precise, and it was demoed drawing and playing a shooter etc. Sony says it'll launch in the spring of 2010, but we don't know what pricing will be like yet.
