Not a bad idea. Digital distribution of FOOL would save on the publishing costs of a physical edition. Hopefully such an option is available.
Personally I am mostly interested in a physical copy of the game, but only for any potential collectors edition that may exist. Unless there is something cool to get my hands on (artbook, map, etc.) then I too would be rather happy with some digital version.
I don't think we will know more about what digital options (if any) are available for a while now. I too would like to see it available on Steam, rather fond of the service.
