George Broussard, head honcho at 3D Realms updated his .plan with some information about their E3 plans. They will not be showing Duke Nukem Forever (DNF) at E3, not as a video, nor in back room demos. Pretty bad news as I am really looking forward to this title and I wanted to see some fresh stuff, but they have their reasons, check his .plan for a little more in-depth explanation.
