Blade has A LOT of production issues right now and supposedly Mahershala Ali is pissed about it all. They're supposed to start filming in November and they don't have a script yet since they started over. There's no way the film releases next year imo anymore and unless they write a good script quick, I wouldn't be surprised if Ali just finally has enough and drops out of the project.
Not to divert, but many have alluded (I assume they have) that 2023 is no longer a viable option for Blade.
The benefactor, is that they have the next 3 months to January to figure things out for Blade, and I have to think it will take what would've been Deadpool 3's spot. And the other benefactor, is that they can take the reactions from WBN, and apply it to the new Blade project.
With how WBN wears its horror badge on its sleeve, alongside the rumored Man-Thing Special for next year; Blade learning from WBN and Moon Knight is a good start.
