No.
I was interested in it, but now seeing the demo, the game has no appeal to me. I didn't play Duke Nukem as a kid, so nostalgia isn't a factor (and that's how it should be). It seems like less of the 'balls to the walls' action and more like 'marbles to the sidewalk'. It's as if the developers said "let's not make this too different from every other modern shooter, guys". Although, I don't really have a problem with regenarating health, to be honest.
I'm glad about this too. There's just so many games coming out that I'm interested in. Like for example right now I have both inFamous 2 and Witcher 2 on my plate, and I have to finish them quickly before the next interesting things comes out.
