A followup novel was released this year called "Year of the Flood"; the story occurs simultaneously with "Oryx and Crake". I picked up a copy of it this week and can't wait to read it. I think a different perspective on things from "Oryx and Crake" would be very interesting.
Right now, I"m reading "Flashforward" by Robert J. Sawyer. It's the inspiration for the ABC TV Series of the same name. I've been a huge fan of the series, and hope the book doesn't disappoint. While I'm on this topic, I also remembered about a novel I read quite a while back from Sawyer called WWW: Wake. Its supposed to be a trilogy and I'm looking forward to the release of book 2.
