HT should make Grievous and show SS how it's done.
I think now would be the perfect time to do it. People are pissed off over Sideshow's product, I'm guessing if HT would show a Grievous figure, they'd be up for that. Then there's the crowd who's waiting for HT all along.that`s if they want to try. might be a job they might be scared to do after this mess.
If HT were ballsy they'd throw out an announcement like they did with their 1:1 Grogu. No figure or prototype or whatever, just some image saying: "Yeah, he's coming" with just the logo on his cape or something, that'd be it. People would know HT is going to make one, instead of just hoping for one.
