Duke Nukem Pre-Order Bonuses Revealed For US

The US version of the Duke Nukem Forever pre-order page has revealed a couple of extra incentives with certain retailers.
Yes, it seems even Duke himself isn’t powerful enough to defeat the urge to sell-out with pre-order bonus trinkets. People who pre-order either the standard of Balls of Steel editions of the game can receive a little extra with both GameStop and Wal-Mart.
For those who fancy something on the homoerotic side, GameStop want to thrust “Duke’s Big Package” in your face, which includes an in-game Ego boost, classic ‘big head’ mode and a t-shirt pack (also in-game, I assume.)
Wal-Mart is shying away from such blatant innuendo and is instead offering a trucker hat (pictured below.)
Neither of these offers appear to have filtered through to the stores in question just yet, but when they do they’ll be available “while stocks last.”

[UPDATE] 2K has also just announced that Duke Nukem Forever will be using Steamworks. This means every PC copy of the game, regardless of where you buy it, will be tied to your Steam account.
