Ah - sorry for the confusion! I think they sort of still exist - but their lack of new products since 2012/13 is somewhat telling. Everything that follows is rumour/hearsay btw - so I'd be inclined to treat it with a grain of salt!
As far as I'm aware the company basically liquidated in 2012, with Vantage buying up the brand name, old stock etc.
Only Vantage itself seems to be performing less than well at the moment - looked at buying John Carter through them, and was warned off by their reputation on the 1/6 scale forums. Looking at their site they're still listing things for preorder that really should be either in stock/long since sold out since March last year. But gods know - as far as I can tell they're still trading! But the rumour mill is going strong!
As for the eBay accounts - hearsay/rumour has it that it's either old stock/the old manufacturer in China continuing to churn the figures out.
Though lately they've been dumping the old fullset stock at megalow prices on evilbay- or rather prices that are in line with what the figures are really worth by modern manufacturing standards! Reviews of whether or not the figures actually turn up has been... Mixed.
I confess that was why I was so very pleased to find old John Carter stock still available through one of the 1/6 parters/resellers that have a good rep - even though I could have risked one of the bundles at Vantage!
