They're letting things settle to see if they still have to do it. Generally, Riot has been honest. Words are wind though.

They very clearly dont want to do it. It was their bandaid solution to keep more people from instaquitting the game when dynamic que came out. I honestly think they have no intention of following up with it, and people will be forced to beg for it for them to make it happen.
