I agree, it's going to be confusing. But there's actually another CHL in the States (Central Hockey League) so I guess you might as well throw another league with the same abbreviation out there.
In the end though, I don't think we'll have to worry about this new KHL. Jamie Heward played in the RSL this past season and he said the 'KHL' is at least 20 years away from being any kind of a threat to the NHL.
He said from the skill level, to the facilities to the travel, it's going to be a major headache to get off the ground.
