Sorry to pick on your post Nick, I know you know better.
I just have the feeling that a lot of Hasbro's issues with this line and others (let's say 3.75" altogether) are of their own making. I don't really recall all that much of the IM lines and how those distributions were, but Thor, Indiana Jones and many others, at least going back to Episode I have been victims of craptastic case distributions. I don't know who the individual(s) involved with determining the ratios are but hopefully they just keep rolling through people because no one has got it correct for a very long time.
It's nothing new.
Yes, I get the fanboys are a small portion of the market. But they continually overestimate the love of kids for 18 versions of the main character. Kids like to have enemies/villains to fight. It's been happening since us old farts had green and brown army men, nothing is new. Not rocket science. Hell, you're better off having a shortage of basic Thor than you are having an overabundance of him. Supply-demand?
Ah, never mind.
