So, one thing I don't think Sideshow counted on with thier NRD for exclusives is the pressure it puts on them to deliver.
So, for me, now I have to be 100% certain I want the statue prior to pre-ordering the exclusive. That of course, is the intended outcome of the NRD. Making sure people arent ordering/cancelling every statue. BUT NOW, an exclusive statue not only has to be of the right character, AND amazing for me to pre-order BUT, the exclusive has to be worth it as well! Art Print's alone are no longer worth the risk that I can't afford it in 6 months and lose $30! Not when I can get the regular cheaper AND with no risk in the NRD department.
Ok, so drop the exclusive edition size and you're good right? Not so much. you have to take into account the loss of the random pre-order that turns into an actual sale for two reasons (which I think happens more then Sideshow realizes). One, a person literally FORGETS to cancel and is too cheap to pay for shipping plus shipping back (which is essentially an expensive and late game NRD). Two, a person has nothing else on order and figures...ehh what the heck let it come.
Now, the chances of either of those scenerios is significantly decreased if I didnt initially order the statue...in fact, chances are I'm not going back and ordering unless the statue (AND EXCLUSIVE FEATURE) turns out to be AMAZING.
Long story short...Sideshow needs to keep the Exclusives awesome now. You put a quarter on the other side of a croc/pirahna infested river and I'm unlikely to attempt crossing. Put a pot of gold and I'll find a way to get it. The risk has to be worth the reward!
