Janaury 14th 2016 Update

Hello people,

Quick question. Will the update tomorrow allow multiple players (more than 2) to team up and play ranked before the season actually starts? Or is champion select the only thing being updated/revamped? I feel like January 20th is when this feature (dynamic queue) will become available but I couldn't help but ask the community. Thanks for listening brosss. Hope I posted this in the right place.
