Beginning with the July 15th 2011 edition of the Watchtower, the society are producing a simplified version of the study copy.
This is apparantly for the many people whose first language is not English, and yet they live in a predominantly Englsih speaking county.
The normal study edition will still be produced but it looks like the cong. will be able to ask for a supply of the simplified version each month.
This simplified version can be downloaded from the Watchtower site.
