I dont think its that bad really to wait a year for a new halo really, Remember the long wait from halo 2 to the game we know today? Compared to that i really don't think its that bad.
By 2009 I doubt the 360 will have long before it is beat out by another console. It's only a matter of time you know.
Are you guys thinking it will be by WINTER 2009? It says in the video if you look closely that it is coming out JANUARY 2009, or sometime in that area.
