Your outlook is misguided. Also the series was still popular before RE4 and CV. RE2 at the time was the highest selling RE game and all forms of RE media were being released including making the feature length movie.
You and Capcom seem to share some kind of fear that the series would shrivel and die if they put their efforts into actually making a game designed like the originals were. Perhaps the series could make due with sticking with a target audience and working on a game based on that. RE6 tries to be too many things, and the only thing that seems to stick out for it is the action which was not what made RE successful.
