Harrowing Legacy Skins Sale 2016?

I have been wondering if the Harrowing Skins,(Underworld Twisted Fate, Zombie Band, etc.) from the last few years are gonna go on sale at Halloween this year. A few years back Zombie Brand was on sale and it was the last day and I just needed a few more rp to buy him, so i really wanna buy him the next time he comes on sale.
