One of my central compliants with the prepainted Wizards Of The Coast Dungeons and Dragons miniatures line was the lack of quality. It was a combination of average to poor paint jobs and uneven poses. As a result, my DDM purchases were almost exclusively in the after-market.
Paizo's upcoming line of Pathfinder pre-painted miniatures has me quite excited. Not only is Paizo staying true to their artistic source materials, but the miniatures paint jobs are much improved compared to the old DDM miniatures. You only have to look at the sample miniatures in this post to see the improvements.
I'm not a Pathfinder RPG player. But i've already pre-ordered the full Paizo Heroes and Monsters set and am looking forward to receiving it in January 2012.
