Virgin Media: At gargantuan video game trade show E3 last week, 3D gaming showed its hand. Sony, with the likes of Killzone 3, is pushing 3D hard.

It looks the business, but questions surrounding the impact of the tech remain. Will visuals suffer if they're in 3D? Is it just a gimmick? Is 3D better than motion control? Here, in a series of micro chats, game developers give us their answers.
