Look near the center of the disc, it has the hologram that all 360 games have. That doesn't look like its just been printed on to the disc. I would say its real as the game went gold 10 days ago, discs will have been pressed since then ready for release on the 20th. Gears 3 is out in 3 weeks, Gears 2, Blackops and many other games leaked to the net 3 weeks before release, I would say its quite possible someone has a pressed copy of Gears 3 already.
The hologram looks real but look at the green lines at the top, the quality looks like shit, something that was blown up a little bit to match the size of the disc. Looking at a retail disc and you'll see it doesn't look choppy or blotchy like in that photo.
True actually, i tried to take a photo of one of my games and zoomed in to 100%, could not get the quality to look anywhere near as bad: https://upload.digiex.net/files/7hxfmaobs1olo6r1avq8.jpg Who ever took the photo didnt appear to know the iPhone 4 geotagged photos with the location it was taken taken. Apparently it was taken here: 52° 1' 42.600000000005821" N, 8° 32' 23.400000000001313" E - Google Maps Google street view: 52° 1' 42.600000000005821" N, 8° 32' 23.400000000001313" E - Google Maps
If the image is fake someone spent a lot of time making a good fake, for no real reason. i'm personally expecting the game to leak anytime now.
That would be the best possibility to make a fake game look legitimate. Also, was their a date on the file, Insane Nutter?
