Handset Flagships: London

It seems to have become fashionable for the world's leading mobile handset manufacturers to launch a Flagship Store in London. Back in November 2004, and way before the launch of the iPhone, Apple opened its first UK store in London, and its first store outside of the US. In November 2006, Sony Ericsson launched a Flagship Store in Kensington High Street, London [although this is operated and managed by The Carphone Warehouse]. One year later, in November 2007, Samsung launched a Flagship Store in Tottenham Court Road [owned and operated by Shasonic]. And now, in February 2008, Nokia has launched a Flagship Store just across the road from Apple in London's Regent Street. So we're missing one major handset manufacturer - Motorola. In July 2006, Motorola launched its first Global Flagship Store, in Shanghai. Then in October 2006, it launched its second Global Flagship Store, in Moscow. Since then, we've seen and heard nothing about Flagship Stores from Motorola. Anyone out there know why?
