Prolific is still deciding whether to charge a small upgrade fee for 3.0 when it comes out. I vote no, since we do plan to charge for "Creature Packs" later on, and 3.0 really just sets the stage for that. Just having a new version come out always triggers a huge wave of new sales, and I'd rather give the existing fans a break. Either way, don't worry about the profits. The Aquarium has been doing very well for 5 years, and continues to support myself, Prolific, Encore, and a lot of retailers in the manner to which we've become accustomed
