It looks like Facebook has started to roll out a new design for the timeline. The Next Web reports that in New Zealand the first new designs have been spotted and ‘our’ people in that region are also seeing the changes appear in their timelines.
The new design is much more focussed on the left hand side column which has been made larger to get more emphasis on it. The right hand side column is made smaller and ‘fixed’. In the header the boxes which showed images have been replaced by cleaner text boxes. It also seems as if there is less personal information been shown right away.
