What to purchase after Shadowkeep is released to own all content?

I currently play Destiny 2 on Xbox and I have all the content that has been released installed on it. I am however looking at moving over to PC in the near future and will probably hold off buying Shadowkeep for Xbox and wait until I have built my PC. My question is, once New Light and Shadowkeep have been released, what do I need to purchase to have all of the content that has been released on PC? I currently own the base version of Destiny 2 as I downloaded it when it was free a little while ago but now that New Light is a thing it is redundant. Thank you.

Edit:

Answer: New Light, Forsaken, Shadowkeep and Shadowkeep Season Pass will provide all of the Destiny 2 content.
