New Stanley Gibbons KGV Catalogue

Hello-

Can anyone review (or point me to a review online for) the new Stanley Gibbons King George V catalogue? It was released around the time of that 2010 London thing that I think I recall hearing something about.

The only snippet I've found is at silverjubileestamps, which says that it has been reported as being basically pulled from the 2010 British Empire. The site's author mentions a value change, an update on John Cooper's piece on the Jubilee stamps, and the inclusion of inverted watermarks.

Is this a fair synopsis? If I have British Empire, can I pretty much pass on KGV?

Anyone?

Thanks.

Collin
