New Skins

Yo Riot,

Just wondering when some of the Legacy skins are coming out. As there was a very Halloween feel to the Slayer Jinx, Slayer Pantheon, Zombie Nunu skins I, and many other League players, expected them to come out either on Halloween or shortly beforehand. Just wondering if there are any updates on when they will be released. (P.S. I really want to buy Slayer Pantheon)
