Can we possibly get a estimate time on the next RGM?

Okay Rito Riot, I've been playing league for like 3 years now. I loved the random game modes, it was fun and exciting. I can understand the reason for taking it away but its been a while since we had one last, I wanted to know when the next one was so i can make sure I'm free to play it. SR is great but people take it too serious at times and its not as "FUN". Aram is cool but can be unbalanced when a team is full of tanks vs full of support champs or any other combos that may of happened. Lastly, twisted treeline the survival of the fittest, guessing only maybe 1/3 of players play. I'm not asking for urf back but any one of the RGM once a month or less, even a schedule, or an update about it. Please and thank you.
