my theory

Hi everyone!happy new year.so i have a theory about the new teasers in zed's sona's garen's and vi's pages.it may sound stupid but i have it on my mind some days now and i want to share it. So if those pics are teasers for a new champion then i think that this champion have a four element theme.lets see why i say that....at zeds pics we see some flower so lets say earth.at sonas pic we see butterflies and..is that smoke coming out of her mouth?so lets say wind.at garens pic it seems like crystals but at surrender at 20 it said that it have a water or crystal effect so lets say water.and and vis pic it seem like a fire theme.i dont know thats may not be rrue its an idea.and also the sound seems more like a thunder than a gun if you ask me but i dont know.may this be a bit changed ao shin?i thought that riot said that next champs are gonna be hummans.lets see :)
