So, as seen in the link, Championship Kalista is coming during the Worlds patch, and so this thought randomly occurred. ARE THE REST OF THEM COMING BACK? In one of the articles @KateyKhaos said that there would be a Championship vs Victorious matchup, so what better opportunity to re-release all of the legacy Championship skin and get this show on the road!

only, 
is limited edition, who might b or not be available at 2016 championship bundle..
Hiya!
To clarify here - The Championship v. Victorious comment was in regards to discussing the difference between the two lines and how you can obtain them.
As mentioned by Mannysmoker, Championship Shyvana and Championship Thresh are legacy, which means it's likely they'll be returning to the store. Championship Riven is limited, and Hippalus mentioned, "Yes I think Championship Riven will come back someday. Most limited edition skins took four years to come back after release, and it's been two years for Riven so far." (We're nearing three this season.)
