I got an advisory e-mail this afternoon. I think a key question is how the electrical charging cable is configured for the different markets (e.g. 2-pin Continental, 3 pin UK, 2 pin bayonet US)?
I would imagine that a multi-adaptor system is supplied for the user to fit the appropriate plug, but if not it might explain the different treatment of countries.
Pure speculation, but no doubt someone will put me right!
