The 'classic toy line' bit is what's intriguing, imho. Since it's 6", I'm sure I won't care about 99% of its offerings, but I've been reasonably happy with the four Legacy figures I've gotten (Khaleesi Dany, Garrik Wildspeaker, and the Dovakhin to become Frost Giants and the albino cat dude to be a giant albino cat dude).
But what classic toyline had so many disparate properties? I can only think of Captain Action and Mego Superheroes. CA was built around one figure wearing different outfits, and I don't see that working in 6" with the characters they name; so I'm thinking it's 6" clothed figures of more than just superheroes, which is where they get the 'Funko twist' bit from.
Meh, we'll find out come Feb. Whatever.
