Since the RE franchise has already branched into multiple game genres (action, rail shooter, FPS, etc.) they could always overlap more than one game at a time under different development teams.
But I'm inclined to agree that the main RE series (next chapter being RE6) should return the main franchise to its horror survival roots, more in vein with games like Siren Blood Curse, relying heavily upon lighting (or absence of light) to establish mood and tone, restricted POVs to create a more claustrophobic feel, limited resources to maintain a sense of helplessness and panic while maintaining some of the aspects of the current games that still work and keep the series current.
If they want to do another action style RE game, then I only ask that they reboot the game play and controls to match the action (fast run and gun, quick reloads, cover and roll system, etc.).
