Sony, where’s the 1.6GHz VAIO P for America?

Sure, we Americans are enamored by flashy designs, but that doesn't mean we don't appreciate performance. For whatever reason, consumers in the UK, Japan and the Principality of Sealand (among other locales) can order up Sony's oh-so-cute VAIO P with a 1.6GHz Atom Z530 processor, while we Americans can't get anything other than the stock 1.3GHz chip. So, what gives Sony? Supply chain problems? Too much haterade? None of the above?
