I can t really speak about resident evil franchise but the re5 doesn t look bad about visual aspect.
but for final fantasy serie i played some of them. Each time i think it can be a complete new way of playing and i m fine with it.
So the final fantasy XII was nice for me even it was not for others.
I agree fews things still need to remain for being the same license, like name of the country or chocobos but other than that... let s see how it will be and let s be surprise.
I know such things can be important for fans but i try to don t paid attention. May be game producer care also too much about introducing new things in gameplay everything so the critic will said it was improved.
