What Happened With Chroma Packs?

So, it's been kinda a while since some Chroma skins did go on the live servers, and honestly, some of the chroma packs were actually pretty nice, mostly the Caitlyn and Zac ones. Though I think they didn't sold well because people don't want to pay RP for skin recolors? I'd like to hear what Riot gonna do now with the future of Chroma packs :0
