That's according to one Dutch retailer, which claims that "Duke Nukem DS" is coming out at some point during Q3. Naturally, you'll all know about the great, big internet joke that is Duke Nukem Forever (a game that almost makes the existence of Sadness look plausible), so you can probably appreciate where we stand on this. In short: "do not believe." And "do not want" also, now that we think about it.
