"earning and rewards system" changes, can we talk about this yet?

When the runes reforged was announced, there was also a revaluation that the earning and rewards system would need to be changed... > Runes today are a significant portion of what players unlock with IP, and making them free will have ripple effects on a lot of other things. Our current earning and rewards systems have a fair share of problems: new players face a huge grind before they can be competitive, and many veterans have piles of IP without anything to spend it on. So we’re going to take a step back and look at our earnings and rewards systems as a whole. We'll talk more about that stuff as we get closer to preseason.

As worlds is nearly here and the preseason is getting closer, when can we expect to hear more on this?

Like many people on the boards, I have some ideas of how Riot can continue to make money on quality products while also making earned items more readily available. But I'll hold off on my speculation and look forward to hearing from the brains behind the game who actually know what is going to be happening.

Thank you for all your hard work, I look forward to season 8 and seeing how these changes will make LoL even better!
