[2020] SEASON 1 ETERNAL PASS : Will it go on sale/when?

Hi, I've been googling for this answer the past two days and I can't find it anywhere. The article that RIOT just released talking about Eternals was confusing.

They stated:

"First off, for those curious about when and how future Eternals will be released, we'll be releasing Eternals in entire Series. This means that Series 2 will release for all champions available at the time in January 2021.

Like our other personalization offerings, Eternals will have discounts similar to those for Champions and Skins, with a bigger discount for when we launch new Eternals.

• 3 months after a Series' initial launch = 30% off that Series Pass for 2 weeks"

Does this mean that Season 1 Eternal Pass will go on sale 3 months after its release date? Or 3 months after this announcement? Or is Season 1 just not getting a 30% off sale and they're ganna start it with Season 2? Because Season 1 Eternal Pass was released Early March 2020, which puts their alleged "3 months after initial launch - 30% off" sale at Early June 2020, which... has already passed.

Did I miss something in the fine print? Or did I miss the sale entirely?

Thanks in advance! ♥
