This wait isn't going to be long as I thought.
On Christmas Eve, Netflix posted an advert for the new season. It had William Zabka - playing his role of Johnny Lawrence - sitting behind a laptop on the Netflix screen of the series.
It had the originally scheduled airdate of January 8th 2021 on the screen, but Zabka indicates that the wait is too long and then adjusted the date to January 1st.
Coincidentally, my Netflix subscription runs out on New Year's Day. I was planning to wait until the 8th to renew, but this news has put paid to that plan.
Instead, I have decided to do an experiment this Friday.
I'm going to wait and see how many episodes I can binge on January 1st before my sub expires.
