C3po will get made when he appears in mandalorian season 7. That may be our only hope.
I doubt we see much more of 3PO to be honest. He's an important legacy character, absolutely, but he's not an incredibly popular character. He was Jar Jar before there was Jar Jar - the character for kids that was probably annoying to many adults. As a kid watching Star Wars on VHS in the early 90s I thought 3PO was funny, as an adult he's just annoying, and a lot of the worst episodes of The Clone Wars have too much 3PO in them.
Hell, even Disney poked fun at 3PO in Rogue One with K-2SO's great line "would you like to know the odds of failure? They're high."
I want a 3PO figure and would buy a 3PO figure. I just doubt they'll do much more with the character that he'll appear in other media.
