But a lot of the new Disney figure selling so well, has to do with the new film coming out! Die-hard collectors are the ones paying $30-60 on eBay, not moms and dads for their kids.
I'm just really skeptical that kids will want to have figures of obscure Indy characters, that aren't very play-worthy! I mean what 6 year old wants a Marcus Brody, Belloq, Monkey Man, Arab Swordsman, Chattar Lal, Wu Han, Maharaja, Lao Che, Donovan, Captain Blumburtt, etc.. Die-hard completist collectors, absolutely... but little kids...I'm not so sure!
You're right, there is not a lack of demand. But that demand is coming once again from serious collectors, who don't make up enough of the market to make a line this extensive profitable. Little kids have to be factored into this, and that's where the serious money will come from.
Metalinvader, the TOD line by LJN was really tough to find back in the day, not to mention there was only 3 figures...that's it!
