The pre-ordering of MInimates, true, may not guarantee that a product will get MADE, if pre-orders are low and the product is cancelled (Bruce Lee, John Wick), BUT if you don't pre-order it, then that is more likely to happen. Also, your preferred supplier may not order enough for you to get a set, and other suppliers may sell out if it does better than they anticipated. If you are not ordering through a local store or one of the big e-tailers like EE, Amazon or BBTS, then you should order through Luke's or diamondselecttoys.com.
Just my opinion, I don't get paid by the pre-order.
