Not sure if this is legit or not, but the Duke Nukem Forever listing on Amazon now shows it available for Pre-order for PC, XBox 360, and PS3 with a release date of February 1.

If it’s true, then it’s not soon enough to keep Duke Nukem Forever off the “Biggest Vaporware of 2010” lists. However, it would be the end of over a decade of development.

Update 12/31: I just checked again (after a comment), and now the date has slipped to May 31st.
