If they're smart, they'll hold of Angelica, if the movie and character do well, they can sell her later, espcially with some solid sales of popular males ahead of her, but if she were to be the next OST figure, this line will sink fast like the last pirates line. You have to be strategic with character selection. HT failed starting the last line with Jack and 2 versions of Sao Feng. Sideshow is STILL trying to sell of Sao Feng almost 4 years later.
Really, of what we've seen in the OST trailers, Blackbeard's the only other character that's got strong sales potential. Barbossa'll be a dud unless they can do his pirate costume. WIth that saide, I wouldn't be stunned if DX Jack were the only OST figure. Sure blackbeard would be cool for some, but with HT's past decisions, if you don't have many characters to do a line of them, why not just DX the sure fire character and move onto other films where you have a greater number of characters to make. OST has about 3 strong selling characters in it that we know of right now, Angelica's iffy and I don't see anyone else in the trailers as standouts, and if one of those 3 will only work with a sepcific costume, if you can't make it, your'e down to 2, or you can just do a solo release of the popular character, make some money off the film and move on.
