Bricklink, which was acquired by The LEGO Group (TLG) earlier this year, has released a video discussing upcoming implementations and website features that will be coming in 2021. I definitely recommend all Sellers and Buyers that frequent Bricklink give the video a watch to see what to expect in 2021.
The Video features the Bricklink VP, Marvin Park, and Julia Goldin, Marketing Director at LEGO.
