George Broussard from 3drealms.com has updated his .plan file with following announcement:

Duke Nukem: Manhattan Project is gold! The masters are being prepared and sent off for duplication now. The game should be out in a couple of weeks, and we'll let you know a more specific date soon. Sunstorm did a great job with the game and delivered the best licensed Duke Nukem game to date. Best of all, for $25 it'll kick your ass, but won't break your wallet. Try it, you'll like it.
