Future of champion mastery

Is there currently any plans of raising the level cap of champion mastery? level 5 is rather easy to obtain and i have it on more than 3 champions already and on my main champion zed i have more than enough to be level 5 mastery twice over and then some. Is there ever going to be like a level 10-15 ect cap? Havnt really found anything else on the boards confirming or denying this
