Yes, you are in the new edition.
There are a bunch of new editions of Belize guides coming out this fall, which should help the many new hotels and restaurants in Belize. Peter's new edition of Rough Guide to Belize (which is excellent) and the new Belize Handbook from Avalon, updated by Joshua Berman for two.
The 2nd edition of my Adapter Kit: Belize will be out in the spring, retitled and revamped as Live Abroad: Belize, also from Avalon. And the new Belize First Guide to the Best of Belize will be out one of these days. I'm also updating my eBook on living/retiring in Belize, Easy Belize.
