When will Conqueror Karma Skin be out again?

So guys I just started playing LoL in the late May and I really like how Karma's ability as a sup or mid. Now I tried so hard to get her full skins (so far I had everything but not Conqueror Karma :(...)

http://na.leagueoflegends.com/en/page/msi-2017-hits-rift This website stated "While Conqueror Karma will return during Worlds and MSI each year, the loading screen border and icon are meant to commemorate players who were playing and watching during the event, so they will not return to the store. You’ll be able to pick up the MSI 2017 Conqueror Karma Bundle for 1616 RP (2208 RP if you need the champion) from April 24, 2017 through May 24, 2017 23:59 PT." So I guess in 2017 worlds, around sep 23rd, this skin will be released for sale again?

Thank you so much for any ideas.
