Perry's did not make their 'Firepower' rules available that come with their 28mm ACW army set, so there is little to hang your hat on that the travel rules will be available to browse pre-purchase.
A lot of gamers already have figures of their choice and so if the rules were free, gamers could simply make up a square grid board (easy to do) and circumvent any money going to the Perrys at all and I doubt the first print run of this game could survive that.
I also think a lot of gamers are think in terms of something being either a figure game or a boardgame, rather than a melding of the two, it is in the area of cross-over that there is a huge potential to explore and I think the perrys have both the vision and resources to do that.
