@Riot When do you guys plan on releasing more levels for the Champion Mastery system?

On Riot's main website, you can see in the loading screen example that there are more ranks (probably working). Could you guys by any chance take some time and respond to this? I know you guys have a company wide NDA about some of this stuff, but these icons are literally on your main website.

Also, there are animations for level ups floating around: https://www.youtube.com/watch?v=WW_R3sYJ96A
