I think there is no point in releasing Resident Evil so often. The game is really starting to get boring with its monotony. Constant war with hordes of monsters.. What's the point? Part 4 will still be the best. Unless you update the engine and graphics, and that’s it! It will be the perfect part of Resident Evil. They couldn't even do normal optimization. On top-end PCs, part 6 stutters. Take the example of Rockstar, look at optimization in games. You just need to start developing the game within 3-4 years. Only a year has passed between Resident Evil installments! You are already starting to fall. The game is getting worse, just like the Need for Speed series.
