All the new sets (except the Fi?ures and the US-exclusives) are on playmobil.de, with links to PDFs and spare parts. I've brought in the spare parts to PlaymoDB, and although these lists are not complete and rarely include brand-new parts, they're still a good start. There are also some extras added to sets that were previously completely inventoried: they're likely to be klicky body parts, subparts or unprinted versions of included parts, or other odd things. I'll get them weeded as I go along.
henry_martini is doing a wonderful job typing up inventories, but I bet he could use some help! Head over to the
sets 2015 thread and add a parts list, for even a small set. I'm not quite caught up to what he's done so far, so double-check the thread before posting.
