Prestige Qiyana skin and Tokens...

Okay so i bought the worlds pass on release and was freaking out that there was a Prestige Riven skin(i am riven main). I played my heart out to be able to buy it with tokens and finally got it. Now, i see the Prestige Qiyana skin and really, really want it. I like Qiyana and its a Louis Vuitton skin so how could you not get it to flex lol. See the problem is, I've already spent all my tokens on the Riven skin and i don't see myself being able to get a whole 2k worlds tokens in like 7 days before they aren't earnable anymore. o o f. Is there going to be another way to get the skin? Prestige Points maybe? Or is there gonna be another event where the Prestige Qiyana skin will be available in the rewards? I will happily get the next event pass and farm tokens to get that Qiyana skin. If this isn't the case, that kinda sucks. I don't have the money to cough up and out right buy her so i would love to earn her. Also, is there going to be any way to get previous Prestige Edition skins like Prestige K/DA Akali? I assume not but i don't really know and would like to be informed if at all possible. <--- ooh those things are cool.
