It depends. I have to place a large enough order with the printer to keep the costs down to an appropriate level for retail sales. The ideal situation is that the project gets overfunded enough that I can place a large order that fulfills all rewards and provides some retail inventory that profit from which is enough to place another large order likely smaller but big enough to get volume discount with the printer. I certainly want to sell them retail, don't know if it will happen...
Probably not. I don't think it makes sense. 1) It will cost you more than $18 to print and make the notebook yourself. 2) It's not something that's useful in pure digital form 3) If you only print and use a few pages of it then you might as well stick with whatever character sheet you are using now.
Yes actually. There are a few page types that didn't make the book because they are too specific - not every player needs them. Specifically, Session Log pages for Adventurer's League Characters. And Spell Description pages. 40 pages of Spell Descriptions would be wasted on most characters. So these page type will be available for download and they'll be form fillable so you can print them out and glue o(r just tuck them in) to your Tome.
Yes. The Tome of Delving replaces your character sheet. You wouldn't try to put more than one character on a single character sheet - even if it fits, it would be too confusing, you'd make mistakes, you'd have trouble finding the right stat. One character per Tome that's the way it works best.
We are actually adding more pages for that (due to playtester comments), the prototype in the video doesn't have these additional pages. There is room for 92 spells in the prototype you saw in the video. We are adding 2 more pages at 60 spells per page which will bring the total up to 120 + 92 = 212
