Project Natal – Microsoft’s answer to the Wii, which allows for motion capture with only the camera

The Microsoft keynote sounds pretty promising. The demo that was used for Project Natal was quite interesting, as it showed a woman looking at the screen and the boy in the game looking right back at her and reacting to her. I’m also a little surprised to see a Left 4 Dead sequel coming out in just a year, but I guess with the amount of success Left 4 Dead 1 gained since last year, it was inevitable. Looks like this fall is the year of monster sequels on the 360 for me: BioShock 2, Modern Warfare 2, and now Left 4 Dead 2 (I guess I’ll also mention Assassin’s Creed 2, Army of Two “2″, Battlefield: Bad Company 2, and Mass Effect 2 as well).
