I still believe there will be a time in the not too distant future when they will combine the KM with the WT "study" version. They could save a ton of paper doing that.
I would be very surprised at that; KM's are printed locally and supposedly written with that particular country in mind.
Having said that it used to say "For Britain" on the front cover of ours and there were differences from the US version on the CD. That label has not been on the KM since 2008. It still annoys me that the WTS call us Britain, they just cannot get it right, it's GREAT BRITAIN. (Despite what HHG says)
