I think it will just bring more hype to the game, when i saw that trailer for halo wars i was like
dam thats good i hope h3's graphics will be like that it just got me exicited for halo in general. I think it was a good ways to get people back into the craze for a new game and we should all prepare ourselves for the soon coming preveiws of h3. Halo Wars is ganna be sweet but Halo 3 will be all the more sweeter, if this trailer is implying that the graphics will be that good.
