Frankly none of the RE games are really that hard, except for REmake (to some extent)
The only thing that made RE 4 easier was the check points, RE4 would have been significantly more difficult if you were sent back to saves instead of checkpoints.
Furthermore I like both styles equally, so I don't want capcom to abandone RE4 style to return to classic style, especially if it would be trash the RE0 was again. Frankly I think capcom should go a bit like megaman during the 16-bit days, RE5 should be like RE4, and they should make a side story game with pre-renderred background that plays like the classic games.
