Id Software is a U.S.-based company. It can't release Doom 3 under any GPL-compatible license until October 2019, when U.S. Patent 6384822 on depth-fail shadowing expires.
Why does it have to be GPL? Why can't they release it under BSD or just make it public domain? What you really mean is that you can't use the code until October 2019 because you won't consider anything but the GPL. I'm assuming you're not bound by U.S. patent law, or the license wouldn't be an issue -- Americans can't use a patent until it expires under any software license.
