Prorate for my pro view?

So I recently got a higher paying job and have a bit more disposable income, and I've been considering LCS ProView as a purchase. However I don't find enough value with the split half over at this point. While researching it I found Riot Games employee who seems to handle their reddit marketing for the product, and they made a pretty unambigous comment saying we should receive prorated pricing as the split progresses. Where can I find this price to decide if I want to make the purchase? Also, for clarity I have appended another link to the verification of this source's credibility.
