Care to give some hints on what you have been planning after the miniatures in the rulebook have been released? Will there be a separate expansion set or will the new miniatures have rules that come in the blister (and are also released online?)
What I would wish are alternate sculpts, as converting metal miniatures is tedious work and Carnevale does benefit from multiple copies of the same figure, especially rank-and-file. Guild players would love several different Pulcinellas, different Venetian citizens would be nice etc.
Or do you want to keep us guessing?
