Destiny 2's newest release

Okay, Destiny 2, is coming out with or has released a new downloadable content. But there are 5 versions, on there website, nothing is specified, which version is for Xbox One. It's not stating, what I would get, for what I could pay for. In the Destiny
2's store, I have the choice to pay for the season, which is around $10.00, for a thousand silver, to purchase the season pass. And/or I can spend $69,99, and purchase the whole content. So, do I have to purchase the season pass for $10.00, and the $69.99,
for all of the downloadable content, or can I just purchase the season pass, or just spend the $69.99, and get everything, in one purchase? This is insane. I can go to Xbox's store, look at Assassin's Creed Origins, as an example, and I know exactly what I'm
paying and what I'm getting. But, this is not the way with Destiny 2. I have no idea what the cost is and what I'm getting for my money. Because nothing is specified. What is going on? Are there any answers? Or should I just give up?
