A post to the Halo.Bungi.Org messageboards gives the full quote in context of the news from yesterday (story) that there is a possibility that Halo, Bungie's upcoming squad-based multiplayer combat game, will be switching from primarily using third-person perspective to become a first-person title. Here is the quote from Bungie's Jason Jones that's reproduced from the current print issue of PC Gamer UK (thanks Shugashack):

"One fundamental change from the game's initial announcement concerns its viewpoint. While originally it was promised to be a third-person game, now a more hybrid approach has been chosen. The exact ration of the two modes hasn't been finalised - clearly, without using Delta Force's window approach, it's impossible to use a sniper rifle in third-person, while driving the bouncing jeeps without the peripheral vision allowed by third-person makes things less enjoyable - but Jason believes that the balance is moving increasingly towards the first-person model"
