GW only went Finecast on their more difficult metal models (for now). The thing is that I like what they did it makes assembly easier, but at a high cost(in pocket for players and them) remember they redid half of their metal fig line in under 3 months had to rework the molds give them the detail, make the packaging, advertise, pay their workers OT, materials, etc. and that cost money. the same would happen to IWM if they did the same thing. as i mentioned above these new Finecast figs 3 advantages 1) no pinning, 2) easier clean up on the mini 3) detail (its a bit better on some figs). Disadvantages: current price which is expected to lower when all pewter figs are released in Fine cast (not gonna happen cause their quarterly "oh plastic is very rare we are raising our prices" excuse will make them keep the current rates)
