I may be jumping the gun trying figure out whether I will do regular updates or a full release this early in the project. I haven't even full introduced a second party member yet. I plan on using that as a measure. Once the party is full I will call that chapter one, then try to have the subsequent chapters match that length and amount of gameplay. How short or long that is will be the best factor to determine how to deliver the game.
My personal preference is to release one who game. Making sure game saves don't break and being able to go back and change things is important, but the major reason is I don't want players to get bored of a dragged out story and delivery.
First things first though. Need to work with what I have. Thanks for your input!
