well I think the PP players will be shit out of luck if they think they are going to see a price reduction. The physical cost of the individual figures will only be a small proportion of the end cost.
When you look at labour, packaging, transport, marketing and R&D plus the company will want to make some profit as well. The initial costs of making the master for plastics is considerably higher as well and since PP doesn't sell anywhere near the quantity of figures as GW they will need to recoup that at a higher % of the price.
