I'm guessing this means the new series is 21XX and not 30XX.The teaser season has begun.
NVIDIA teases upcoming Ampere series for August 31st
An Ultimate Countdown has started. A mysterious teaser has been published by NVIDIA on social media. The company has not revealed the name of the series, nor did it confirm the exact launch date.
A video teaser posted on Twitter is accompanied by a background image on the official NVIDIA profile page. It says “21 Days. 21 years.” This cryptic message refers to August 31st. This is the same date GeForce 256 was released in 1999, exactly 21 years ago.
