Considering the fact that I haven't been able to find an entire wave of figures in an actual brick-and-mortar retail store since the Vintage TPM wave in January 2012 (not even kidding), I certainly don't see the distribution issue improving enough for me to even worry about what Target is charging since i haven't been able to find anything there anyway.
That being said, the price increase will likely spread, since Star Wars figures are in such short supply there's no need for TRU or Walmart to actually decrease their prices to compete with Target. After all, if Walmart can't sell those Ric Olies and Mawhonics at 10 bucks, they're not going to sell them at 12-15, so it won't hurt to mark them up. TRU will have their mountains of Biggs and Anakins that they'll mark up, and the vast majority of the new figures planned, if they get released at all, will ostensibly become online exclusives just like the vast majority of the last three years' figures.
Am I being overly dramatic/cynical/pessimistic? Perhaps. Maybe. Sure. All I know is that Hasbro has managed to suck most of the excitement and joy out of (their segment of) collecting these last few years with these types of moves from which they never seem to learn. For me to expect anything less than a complete cluster**** from them at this point would be akin to expecting my ******* to sing showtunes.
I'll be taking that 12.99-15.29 they want for a Chewbacca that would likely be cross-eyed and possibly have two left feet and spend it on more Lego Stormtroopers, thanks.
