Buy BO6 Now or later?

I have Black Ops 7, and while I enjoy it, I'd like to buy Black Ops 6 because I like it even more. ( I tried it with Game Pass) However, I want to play BO7 until the end of Season 6 so I get my money's worth out of the game. I just don't want to feel like I wasted money and leave it behind.

That's why I'm torn over whether I should buy Black Ops 6 now or not. It's on Steam for $28. Should I buy it later, and will it likely go on sale soon after the Black Ops 7 seasons end or just buy it now?
