The first problem is that the 6" figures are over priced by about $5 right now. If they want people to adopt the line, they need to bring it down a little bit... $17.99 even.
I agree with you... but Hasbro doesn't. In fact, not only are they not
lowering the Star Wars 6" figure price for 2014, they're bringing their other 6" figure lines into the $20/boxed world too. Both the 2014 Spider-man Legends and Capt America Legends lines will be boxed/$20 instead of carded/$15. BBTS recently posted this note: "Please Note: Hasbro has raised prices on all 6" Marvel Legends Figures and the new MSRP is now ~$20 per figure."
I could see the price for Jabba with dais for about $50-60 due to the fact the he and his throne would have a lesser part count than something like the speeder with scout trooper. Sure, there might be more plastic but I think labor for assembly could keep the price down somewhat and 3x the price of a single 6" figure seems attainable.
Jabba with a Dias would probably be expensive. At least $60. I bet it would sell like gang busters though. I think the 6" line is more collector driven than kid driven at this point and collectors would gobble that up.
Depending on the packaging, I suppose they could get the price down. But ultimately, how many folks out there are even willing to plunk down $60 for a 6" scale Jabba Throne set? Like gang busters seems a bit excessive. Does anything $60 sell like gang busters anymore?
I'm not much of a 6" scale collector, so I don't really know if there's any type of market for this kind of thing. I guess He-Man would be the closest comparison since that is one 6" line with vehicles and playsets and things. There you're talking about $35 mounts or $50 vehicles (neither with a pack-in figure) in a direct-to-consumer model.
Like I said before, I'm not collecting this line, just watching it unfold as an insight into the 'new' Hasbro. It'll be interesting to see if the collector folks who bitch about a $60 vehicle being too expensive will be willing to pony up $60 for a 6" Jabba w/Dais.
