Bungie's Frank O'Connor stepped out for a quick break and said that what has been considered by some to be less-than-stellar graphics (especiallly when compared to Gears of War) in the Halo 3 beta are not what we'll see in the final build. He believes "folks will be happy with Halo 3's graphical polish come September." The controversy over the graphics dates back to the beginning of the Halo 3 beta where some people noticed that the upgrade from Halo 2 to Halo 3 was less than expected. There was even a comparison video made (also available in HD at GameTrailer's site).
O'Connor points out that nobody is complaining about the gameplay and that nobody has seen the game in its complete form. He says at this point they are just polishing a game that is "largely complete." He says that Bungie learned some tough lessons from Halo 2 and they aren't looking to repeat them in this sequel. He says they focused on planning this time around it will mean "more features, fewer cuts, better polish and a more intensive test cycle." O'Connor could have just saved his breath and released an HD video of Halo 3's single-player campaign and put the whole thing to rest.
