Thanks darksilver for your comments and observations. It maybe that when Andre Schofield made his comment about 60 years in London, he was just thinking about 60 Years in Mill Hill. But certainly the major lie there was about the increased demand for bible literature being the reason they are moving.
Actually I think most JWs would know that at least in the uk, there certainly is less demand now for literature, as so much of it now comes electronically.
