sorry but that's just not true. Sideshow NEVER take replacement parts from new stock or do exchanges for a new statue. They have a new stock all boxed etc.. for new orders only, and a separate stock (just different parts) for replacements. They will never ship you another new statue as a replacement.
This is directly from their customer service, for one of my statue only way I could get a new one (because the replacement stock was colored differently) was to return the existing statue for a full refund, then get the cs to place another new order for me. Even he acknowledged it's rather stupid as oppose to just ship me a new one, but said that's the only way to do it within their process.
but i expect some cancellations given all the new statues coming out, so you will probably get converted. I know i was surprised when my cap pf ex converted... (after i already ordered a reg version

)
