Once it's free, who is going to take care of it? For free?
Does RoadShow need daily caring? I mean, I is mature project which is presumably out of beta stages since many years. If you were going to develop completely new features it could be another bounty project again.
This won't be as much fun as having some sort of carrot providing an incentive to keep pulling the cart.
I dont expect Amiga software is going to sell more than 50-100 copies in total these days... most of sales happen when product is released and then stagnate to very low numbers. In few months you have saturated entire Amiga market and it is not growing.
It is your choice of course but in my opinion with limited market bounty generates more pleasure to both users and developer.
