Updating my list again.
NOTE: In almost every sale we have a new skin that was never on sale before. A skin will probably go on sale faster if it's not selling much (like Pharaoh Nidalee), otherwise it'll more or less follow the order of the release date. I'm almost 100% certain that all skins released before Dec 1st (except Professor Ryze (released on 05-Oct-2010) and Pharaoh Nasus (02-Nov-2010)) have been on sale already. So, the list below has probably 1 skin from next sale (unless, finally, Professor Ryze or Pharaoh Nasus go on sale).
- Dec 01: Blade Mistress Morgana (975 RP), Brolaf (1820 RP), Junkyard Trundle (975 RP), Lil'Slugger Trundle (520 RP).
- Dec 06: Surfer Singed (975 RP), Primal Udyr (975 RP).
- Dec 14: Desperada Cassiopeia (975 RP), Siren Cassiopeia (975 RP).
- Jan 04: Surgeon Shen (975 RP), Nurse Akali (975 RP), Sheriff Caitlyn (520 RP), Resistance Caitlyn (975 RP).
- Jan 10: Sailor Gangplank (975 RP), Pharaoh Nidalee (975 RP).
- Jan 18: Commando Galio (975 RP), Dreadknight Garen (975 RP), Outback Renekton (975 RP), Galactic Renekton (520 RP).
- Jan 24: Lumberjack Sion (520 RP), Vandal Vladimir (975 RP).
- Feb 01: Sakura Karma (520 RP), Sun Goddess Karma (975 RP), Lion Dance Kog'Maw (1820 RP), Djinn Malzahar (975 RP).
- Feb 07: Almost-Prom King Amumu (520 RP), Prom Queen Annie (975 RP)
- Feb 16: Longhorn Alistar (520 RP), Totemic Maokai (520 RP), Charred Maokai (975 RP)
- Feb 21: Vandal Twitch (975 RP), High Command Katarina (975 RP)
1) All skins NOT bolded or underlined were on sale already.
2) Underlined: Skins that will never go on sale (legendary or limited like Kitty Cat Katarina and Lollipoppy).
3) Bolded: Skins that will go on sale eventually and probably soon. So, don't buy those unless you really want them NOW (and, if that's the case, don't complain if you bought it and it is on sale like 2 days later).
