I saw the IGN article when i got home today.
It made me laugh because the xbox 720 was made up by a fan then the fan just made a fake system pic and included halo 4 box image(along with about 5 other people). I dont buy it nor do i really care if there is a halo 4. It was "Finish the Fight" Next is "Start a new Fight" or what ever that video about the world domination of halo said....
If there is a halo 4 it will be on 360 because of how much Microsoft is putting into the 360, they would loose several thousands or millions if they were to do that because so many are buying 360's right now because of what is soon to come...
lots of people do that stuff for attention eh
Hints all the "fake trailers" for things.....
Ya, YouTube is a dumping ground for those.
But I really do hope that there is a Halo 4 (or whatever other name they give it) since I'm always happy to have another good game.
