I'm not sure there'll be an EX, but if there was, I'd think the easiest thing would be an alternate weapon. My guess is that she's the EX though.
Overall I think the sculpt looks great, the paint looks awesome, the armor looks really cool, and she's unique, but it just doesn't grab me and say, "Buy me!" at first look. Maybe that'll change when the piece is shown as a whole during preview night, but I'm at the point with so much coming out that if it doesn't grab me that way when I see it as a whole, then it's likely best I move along.
She looks like she'll fit in great for those with the Court of the Dead line! She looks determined and ready to go. I'm eager to see a preview of her, but I think I'd be more apt to go another route looking for a badass, female assassin!
The detail Sideshow is putting on some of their armors lately is fantastic! This and Masters of the Universe both look to be knocking that out of the park at the proto stage, and Machiko's production photos show that her armor looks superb. Really happy to see that level of detail in certain pieces moving forward!
