Well there is still the "Wandering Minstrel" mechanic in the game. While I'm pretty sure the original Coil 1-5 difficulty will vanish, it could be replaced with a newfound difficulty with differing mechanics later on.

Fact of the matter is, though, that many players are done with repeating Coil 1-5 and are ready to move on to the next part of the story while others are struggling with Coil 1-5 now and will be able to complete them in 2.2.
