I said "undecided". I've already got too many options and need to cull a lot, so too much crunch is a bad thing. So, if it's more focused on things like ships, ecologies, drowning/swimming/etc. rules than PrCs and feats, that's a plus. Also, I'll have to see whether it's more about waterborne/locale adventures for air-breathers or for underwater adventuring. I've never run an underwater adventure, have no interest in them, and can't see that changing. But sea travel and environments are ubiquitous.
The more there is that involves coasts, rivers, and lakes, the more likely I am to buy it. The more it talks about crossing great oceans and underwater adventuring, the less likely I am to buy it.
