Doesn't seem like you can edit comments so I'll add: Sony's focusing on the games with Microsoft focusing a bit more on the OS and such because those are the advantages each one has. Sony leaned heavily on first party in that conference. Technically Microsoft did too I guess, but attached it to this ecosystem it's trying to build. The Xbox Live ecosystem is how Microsoft beat Sony last gen, and with fewer exclusives it's what Microsoft is trying to leverage now. Lastly, that's just what Microsoft is — an OS company. Windows is still a way bigger part of Microsoft's business than Xbox. Sony probably can't survive without PlayStation at this point.

On the flipside, it absolutely makes economic since for everybody else to be playing to the investors. That's what E3 was made for. The original audience was always retailers, investors, and the mainstream press that usually doesn't turn its attention toward video games.

Actually let me also say for a bit that the PC Gaming Show might have actually been just as much "for the gamers." A lot of it was updates for games that are already out, and a ton of it was basically a talk show with the developers.

But anyway, a more important thing to note is that Microsoft, Ubisoft, EA, and Bethesda at least showed off more stuff that we'll actually be able to play within the next nine months.
