I find that Arbor aren't very good at describing their boards. I have a Coda and held the Wasteland in my hands. These boards aren't really comparable even though the description on Arbors website could make you think so. As seriouscat said, the Wasteland feels stiffer. That's not on-snow experience though. Just what I've found during flex tests at a store.
On that note I am going to go with what I know, and I know I really liked the Coda.
