There are going to be dozens of great games at E3, sure. But this year’s event is more about exploring the barrier between users and machines than anything else.

We know Project Natal will be in stores sometime this holiday season. Now, we have a more specific timeframe – October.

The short answer is we don’t know, but Microsoft may be developing a game under the name Good Science.

Side-kick, a team formed by Double Fusion, Eidos, and PrimeSense (that’s the company behind Project Natal’s technology) leads, announced they are developing games for Project Natal.

PrimeSense proudly announced their 3D sensing and recognition technologies are being used for Project Natal.

Wondering what Project Natal looks like out of its plastic shell?

According to a recent report, Nintendo president Satoru Iwata declined to adopt Natal’s camera technology as part of the Wii hardware in 2007.

What is “viral gaming,” you ask? Think Mafia Wars. Microsoft is investing in this strategy as a way to tell friends about a game and as a gameplay mechanic.

MCV has a scoop on Project Natal from a “secret” developers tour. According to their sources, the device will launch in November 2010 with fourteen titles.

Because that’s what Eye mix sounds like.

Microsoft sent out a press release with a list of developers working on games for Project Natal. RPG behemoth Square Enix is one of the publishers on the list.

Morning news magazine Mezamashi TV got a pre-Tokyo Game Show look at Project Natal. Watch Fuji TV announcer Yoko Shono play a game of Ricochet with Kudo Tsunoda and try the controller free racing demo Microsoft brought to E3.

Microsoft’s final announcement was the controller free environment called Project Natal. We saw a demo of a player waving her arms to bounce balls into a wall and someone shouting out colors to virtually toss paint on a canvas.
