And you're right, so many games I'm waiting for have been pushed back. Bloodlines 2, Gotham Knights, Suicide Squad: Kill the Justice League... I hope the wait will be worth it here.
Though, depending on your taste, you can try other games in World of Darkness, too. As I mentioned, I was not hugely impressed by the Coteries of New York, but there is also Shadows of New York, for example. My main issue here is that they are too focused on the narrative and not enough on the gameplay (Telltales did that, too, but even they didn't have it at this level). But if you don't mind that, those games can be good, and do not need much in terms of hardware.
Any particular reason why you chose Geforce RTX3070 OC 8GB? If you want, you can ask everyone for advice here, see what other members think.
And yeah, Legion Slim 7 is great! 😉
