I really, really wouldn't count on it any time soon. Given the pandemic, it's tough to say when it'll be back in stock as suppliers cannot provide parts to assemble the phone. And even if it does, there are many people that will literally buy it the moment it's available. I'm willing to bet if it ever does get back in stock, it'll sell out in minutes just like it did when it was first released. I actually read somewhere that it was sold out in 30 seconds or so.
If 5G doesn't matter to you, you're okay with not having specific bands, and are willing to flirt with the idea of no real warranty from OnePlus - I'd recommend you look into the IN2020 version. The 8Pro with 256GB of storage can be had for 903$ right now from trusted seller never-msrp.
I should've bought one in hindsight instead of paying a ridiculous markup on a used IN2025, but the one I snagged came with the much desired wireless warp charger and plenty of goodies, so it didn't sting as much.
