So, in the past, it’s been said that this series would be following Loki over the course of hundreds of years and how he’s messed with human history. But, we have a new wrinkle in that this series will follow the Loki who escaped with the Tesseract in Avengers: Endgame. Meaning that this Loki will lack all the development our Loki had before getting his neck snapped by Thanos in Avengers: Infinity War. Additionally, that also means that this series will actually be taking place in an alternate timeline.
Kevin Feige said this series would explore the mind-set of this Loki post-Hulk smashing. So, his development might take a different direction from the original. It could also possibly end up linking up with Thor: Love and Thunder in someway like WandaVision will with Doctor Strange: The Multiverse of Madness.

While not much else was said about the series, the logo itself might be implying that we’ll see at least four distinct time periods throughout the series. I guess we’ll find out more before Loki releases on Disney+ in Spring 2021, alongside Hawkeye and WandaVision the same year.
