Compared to, say, Spiderman, the number of Voltron toys around today is pretty sparse. Having done some digging into this, the reason seems to be a worry of supply and demand - manufacturers don't believe the audience is there. Prototypes of new Voltron figures were on show at the New York Toy Fair in 2018, but these figures have not been released. The limited number possibly explains the high-end and fluctuating price of some Voltron toys.
