3D Realms Closing?

3D Realms is shutting down according to a report on Shacknews that's confirmed by a post on the 3D Realms Forums by Joe Siegler, who says: "It's not a marketing thing. It's true. I have nothing further to say at this time." 3D Realms has been otherwise silent on this topic so far, but publisher Deep Silver and newly formed Apogee are unaffected by the news, as they say: "Deep Silver and Apogee Software are not affected by the situation at 3D Realms. Development on the Duke Nukem Trilogy is continuing as planned." According to Shack the closure is due to funding issues, and they have a statement from Take Two who claim to still own publishing rights to Duke Nukem Forever, but that they have not been funding development of 3D Realms' flagship game.
