When you say "next," it means, immediately after. It refers to an event that will take place immediately following the current one and the one referenced.
When you said the Darius rework was "next," I imagined it would come before the Gangplank one, or the MF one, or the Fiora one, or the now TEEMO one on PBE.
Yes, Teemo rework. He can throw shrooms at your team now, god bless
Blue Socialist1 votesJust like Ao Shin, unexpected things can come up in development that delays it significantly

He's never coming.
Never.

I'm pretty sure they've said they haven't even begun development on his kit at all yet, not even conceptually, he was announced as being after 
since then there has been 10 releases 
honestly it doesn't take a rocket scientist to realise that he's probably never going to be released
Blue Socialist1 voteson hold is not the same as completely cancelled. Just because it's not coming soon doesn't mean it's out of the question entirely. The difference between Ao Shin and those other champs you mentioned is that they talked about him well early in his development while other champs are revealed when they're practically finalized.

Dormidon1 votesI'm so dissapointed Rito. Rework Fiora and Teemo intead Darius. Fiora at least has 52%+ winrate.
