In fact this discusion reminded me of a video I watched a while ago about the release of a new technological device

As others have said, I also want to buy a book, even if I don't play the game often or at all. I bought "Hail Caesar", "Napoleon" from Foundry, "Flames of War", "Lost Battles" and I am quite happy with the purchases even if I will not be playing (DBMM was my last one disappointing: I won't buy any more black and white poorly presented rule systems). What I demanded from V2 was a substantial change in the book (not the rules, actually), with new diagrams, clarifications, new pictures, some new illustrations and a few add-ons in the wargaming part, which right now is quite poor. Even a couple of scenarios instead of the example of armies, which are totally innecessary in V1.
What I have a hard time to see is why a book on demand would not be profitable (or at least cost effcient). I think that all the people that posted in this 9 pages wanted to buy a book. The publishers can open this on demand system and set a number which could be profitable. Then it is up tp players to get that number of reserved copies so that they can have the book they want. You can even release the V2 right now as an application, have it working for a year until the print is ready and then decide to publish on paper with the last corrections (which there will be). There are options and that way you can set the problem in the other side. If there are not enough reservations you can come back here and tell the players: See? It was not profitable.
In the other hand, I think that army lists are better on online forms than on paper, as experience has shown. They would be good if they were other than lists, as for example army books in Warhammer or Flames of War. That encourage new players to buy them. But right now It is quite hard to convince a new player to get to buy one of those books when they only need one page (and they won't need any other really because they own and will own only one army). Maybe, instead of whole army books you can sell army list applications and thus you buy Early Imperial Roman for a very cheap price 0,5€.
