Good points Nick. I'm curious if something similar happen with the Rancor. I checked this morning and it dropped to 4,769 backers and just checked again a few minutes ago and saw it's 4,770. Did it hit bottom? I don't know, but I do expect a surge towards the end, because that always seems to happen.
As someone who primarily collects the 3.75 scale, of course I'm biased that I want Hasbro to focus more on that scale. Looking at the Razor Crest, it would seem that scale is more popular, but I have a feeling that has more to do with the vehicles being so popular and the 6" scale just is not conducive to vehicles. (Although a 6" scale Falcon would be absolutely glorious!)
