If there's a Rutger Hauer cameo I'm going to vomit. Other than that, sounds like a great idea
I'd say I'd like to see more of the L.A. of the future, but thanks to the seminal influence of the original's visuals upon sci-fi en masse in the years since, I dunno' that that is a requirement for a sequel. I just hope/expect it to look great and be more interesting than anything starring The Rock.
