whats the old saying again "you can't please everyone all the time but you can please some of the people some of the time"
that said, and speaking as someone with no real emotional investment in the series as i haven't played it, just go ahead and reveal her face, knowing what fanbases are like if her face isn't what they envisioned it would look like they'll write it off as 'never happened' anyway
and besides, there is already far too many instances of developers having to tread lightly on eggshells in order to try and please every single member of a games fanbase to the detriment of the final product
