But honestly? What are these front-men supposed to do? Their main lot in life is to read from/memorize a script that's fit for general consumption.
Furthermore, at this point in time, anything about the game itself is subject to change. Will "Mila" and "Rig" even make it into the final version of the game, let alone be actually named as such? Or what if the listings for Pai and Sarah are only half accurate, because only one of the two actually made it into the final version of the game?
It's all a bunch of conjecture, but again, for most PR guys and girls to be as far away from the actual game development, it's honestly "safer" for them to just not comment on such things. If people get butt hurt by some future development down the road, the least that Tecmo and Team Ninja can say is that "we didn't go on record to confirm things one way or another~!"
In short, CYOA is definitely in play here, just as it is with any other line of business.
