It's not the demo of DMC4, you can clearly see from the instalation screen, which is not present in the DEMO (for obvious reasons), and the first mission. Besides he shows the game instaling without the BD, and that cannot happen if you remove the disk from the tray. As seen on the video, the PS3 is empty since minute 1.
Even if you can't understand Portuguese, you can clearly see there is no media inside the PS3 tray, and yet there it is, DMC4 on the screen. He even pressed the eject button to prove there was no disk and removed thee HDMI cable to prove it was that one PS3 which was connected to the TV; he also shows the place to prove there is no other PS3 hidden.
Great job, I have to get that program!
"GT5 isnt true 1080p. its 1280*1080 something, also due to console limitations it dips below 60fps."
You're thinking of Prologue. GranTurismo 5 will be 1920x1080 pixels, progressive scan, 60fps on most of the time.
