Developer 3D Realms has publically stated on their official forums that a teaser video for Duke Nukem Forever (in development since 1997) is expected to release tomorrow.And all I have to say to that is: I've got balls of steel.
As series co-creator George Broussard put it, "After seeing the teaser we thought it was something we should share with all of you and while it's just a teaser, rest assured more is coming." He went on, "Tomorrow, Wednesday the 19th, around noon CST, we will release the first teaser trailer from Duke Nukem Forever."
UPDATE: They were serious.
