There's a decent chance Year of Prophecy Ultimate Edition gets taken off the store after June 9th. Originally, it was meant to include a major update Shadow and Order... which has now been cancelled since Bungie is ending development on Destiny 2 entirely. If you want the Ultimate Edition rewards, grab it before June 9th just to be safe. But heads up: you'll only have access to the upcoming season pass. The first three are already basically gone. You can't claim rewards from passes that already ended. The current one is going to end before you could physically earn it all. So weigh that before you buy.
