So, if you ask pretty much any member on BZPower or other LEGO networks, chances are they will have at least one prototype piece. Now that BIONICLE has been over for a couple years now, I still have yet to see a Hero Factory prototype piece. I haven't found one in searches or discussions, and am wondering why there aren't any floating around in the world.Surely LEGO still uses prototypes to design new pieces in themes, especially in ones like Hery Factory. If that's the case, where do they go afterwards?If anybody has seen one, has one, knows about one, or anything, I'd be glad to hear about it, and I'm sure others would as well.
