When is the new ranking system coming?

That’s all I want to know 343. I’m tired of playing just for fun. I can’t help myself but to try and compete, but it’s impossible when all these things get on the way of it. I’m not that good at Halo, and right now, I don’t feel motivated to get better. I feel like I’m just wasting my time. So a little update on this thing would be great! =)
