From the interview:
"3D Realms' involvement in the creation of successful franchises is often overshadowed by Duke Nukem Forever, which is unfortunate. 3D Realms is more than just Duke Nukem Forever.
I can say that we have a big announcement coming in the next four weeks, and I'm not sure, but I believe we have another major announcement coming in the next four to six months... while I can't say exactly what these are, are they about Duke Nukem Forever? No."
