I think she will because she doesnt talk in the games cutscenes, you only read what she is saying. Her voice actress may be either English dubbed or A Japanese voice.
She talks in Gravity Rush though?
There's a few cut scenes. it's not all comic book crap.
It's subbed in in Japanese, with an actress giving off a french accent.
Kat did have a bit of voice work in her game for her various yelps and grunts (which I hope returns in PSASBR), but I'm not sure what they'll do with her being mostly mute either.
I think I'd also be fine with either speech bubbles or a "mute" cutscene (such as the one where Kat first meets Raven), as either one represents the game well.
In actual gameplay, not much talking will be needed. Her moans, grunts, and yells will be enough since it's a fighting game. As for the arcade mode, they can use a narrator just like they do for Sackboy.
