I have it on good authority from two different sources, one is a major player in Subaru tuning game, the other is my uncle who is a machinist on contract to repair Subaru engines for a dealer in Boston, that the ringlands in the 2011 and up EJ25's now have a ceramic coating on the ringlands to help reduce failure. It's very non scientific though, take it as a grain of salt, the engineers from Subaru haven't confirmed this.
